While external crash damage to a vehicle is clearly noticeable, other parts are less so and therefore require thorough checks and repairs before a car is deemed roadworthy and safe to drive.
A car’s powertrain comprises several important components that are prone to serious damage if a vehicle is unfortunate enough to be involved in an accident.
In most modern vehicles the powertrain includes the engine, transmission, drive shaft, differential and the final drive. Together, these components transmit the engine’s power through to the road surface.
Our workshop technicians have been kept particularly busy recently with two Jaguars XJSs that were both involved in serious accidents. In each vehicle, part of the powertrain (namely the differential), had suffered serious internal damage.
The differential allows the outside wheels of a vehicle to rotate faster than those on the inside while still transmitting power to both. This is necessary when a vehicle is required to turn, allowing the wheel that is traveling around the outside of the turning curve to roll farther and faster than the inside one.
(This fascinating video from the 1930s explains the principles of the differential gear)
In one vehicle, part of the gearing teeth on the differential had broken off causing a terrible noise as they were caught up in the mechanism; the other caused the limited slip clutches to fail resulting in one of the rear wheels to skid on every corner – unnerving to say the least!
Differential damage can be caused when a car is struck head-on or from the rear. When this happens, and the gearbox is in Park, the only thing stopping the car from moving away is the ‘tyre-wheel-halfshaft-differential-propshaft-gearbox’ chain. Surprisingly, the differential is the weakest link in this chain.
If the gearbox is not in Park, there’s usually enough inertia in the chain to result in damage caused by a strong collision, even before the wheels begin to roll forwards or backwards.
Our advice to you is that if you are aware that an unavoidable rear end shunt is about to happen, apply as much braking as possible while obviously paying due attention to your own personal safety, and to the safety of any passengers. This will, to a certain extent, protect the differential.
If you know, or suspect that your Jaguar XJS has been involved in a collision then it’s essential to have a thorough safety inspection carried out by expert technicians.
For all used classic Jaguar and Aston Martin cars, we carry out a comprehensive two-hour, on-site condition assessment. For more information, visit our website here.
Unsure of your differential differences? We list the various specifications below, courtesy of jag-lovers.org.
Salisbury 4HU Powr-Lok
From 1976-1985, the differential was a Salisbury 4HU Powr-Lok that came with either 3.07:1, 3.31:1 (1976-1982), or 2.88:1 (1982-1985) ratios.
From 1985-1987, a 2.88:1 DANA unit was used for the V12. This unit can be distinguished in that the bearings on the output shafts are held in place with three bolts; the differentials both before and after these years have five bolts. It also has no drain plug.
GKN Power Lock
Beginning in 1987, there was a differential referred to as the GKN Power Lock with a 2.88:1 ratio.
Last year, we worked on many amazing classic Jaguar cars, which makes it difficult to choose our favourites. However, we hold a particular soft spot for this project, and are extremely proud of the finished result – and its owner is delighted, too!
It’s not everyday that we receive a car from Norway, but it goes to show how much some Jaguar enthusiasts are willing to go to get a decent restoration. Our car of the year, an X305 with 6-litre V12 engine, was shipped from Norway with an extremely comprehensive restoration brief – we like a challenge!
As part of a full-scale restoration project, we conducted an expert evaluation for internal and external re-engineering perfection.
We fully stripped the vehicle, top to bottom, inside and out. Our expert engineers rebuilt the V12 6-litre engine, as well as suspension, braking and steering systems to ensure maximised driving pleasure.
We didn’t stop there, as all new leather interior was fitted, with Alcantara headlining and sun visors, complete with an audio system upgrade boasting seven loudspeakers and subwoofer in the boot. All interior and exterior lamps have been converted to LED types, with HID quad headlamps.
The car also had significant rust problems, which were addressed appropriately. The result has to be one of the most luxurious and powerful saloons on the road. The extraordinarily smooth and powerful V12 makes most modern cars feel inadequate.
The interior is now a soft and welcoming abode, with the seductive aroma of fresh leather. A true masterpiece both of Jaguar’s design and our restoration techniques.

Classic cars have excelled as an investment asset class, with the value of the Historic Automobile Group International index rising by 16% in 2014. Yet it is more ‘modern’ vehicles that are able to grow in value and are attracting investors’ attention. Managing director, Chris Knowles spoke to the editor of Investment Week about which classic cars are best to invest in.
The full article can also be viewed here.
The classic car market is now worth more than £6bn in the UK, employing thousands across the country as demand increases. This growing market falls in line with the fact that more motorists are turning to classic cars as their vehicle of choice.
Owning a modern car can be frustrating, as its value depreciates rapidly within the first 12 months of ownership. Comparatively, a classic car is more likely to retain its value – it may actually increase if restored and maintained to a high standard. For some, the decision is driven by nostalgia, while for others it may be the desire to stand out from the crowd.
The Knight Frank Luxury Investment index recently noted that classic cars have beaten everything from art, watches, gold and coins over the past one, five, and 10 years (see chart, below).
The group noted that the value of the Historic Automobile Group International index has risen by an astounding 487% over the past 10 years and grew by 16% in 2014.
These strong returns have pricked the ears of many eager investors looking to benefit, but which classics are leading the way?
Choosing which classic car to invest in can prove costly – particularly as the market is becoming increasingly lucrative. Big name Ferraris and Lamborghinis are likely to set you back a hefty sum. Last year, for example, a 1962 Ferrari 250 GTO sold for $34.65m at auction – making it the most expensive car in history.
Owning such a pricey vehicle takes the fun out of classic car ownership, as there is no way you can take this million dollar supercar for a quick spin without instantly depreciating its value.
Yet classic car investment need not be so costly, as current market trends point favourably in the direction of more affordable ‘modern classics’.
Cars from the 1970s to the 1990s are beginning to make up ground on their predecessors, with classic Aston Martins, Ferraris and Porsches inevitably holding their own. If you are looking for a solid, long-term investment, however, one marque stands out among the sea of its competitors: Jaguar (see table, below).
When thinking of a classic Jaguar, we arguably think of the iconic E-Type, which continues to set investors back a large sum, without much of a return on investment. Its somewhat lesser known, younger siblings – the XJ-based models of the 1970s-1990s – are making a well-deserved resurgence, as their value begins to increase in line with growing demand.
The stand out investment of the moment would have to be the Jaguar XJS, which recently celebrated its 40th anniversary. Throughout its life, the XJS was a car that confounded critics, but won over enthusiasts and succeeded in returning its investment to the company.
Considered by many as an unworthy successor to the E-Type, it proved its worth by achieving a longer production run and outselling its predecessor by 43,000 cars. In recent times, the XJS has arguably become more desirable than ever, and even at 40, its price continues to soar.
Taking into account data collected from Classic Car Buyer, many XJS models in A1 condition have increased in value by up to five times since 2013, as seen below, and the XJS continues to be named as one of the hottest modern classics to invest in right now.
It is firstly important to consider that sellers – in particular garages and dealers – will have gone to some trouble to make the car look pristine on the outside. A perfect-looking car is often in much worse condition than one with visible rust, which has not yet been ‘tarted-up’.
As with all cars made of steel, the most important area to consider is rust, both the less visible painted areas and, more importantly, the hard-to-see underside and hidden cavities. The most expensive part of a restoration is usually the stripped re-spray. If you are careful in selecting a low-rust car, you could save around £10,000.
City cars are often in worse condition, as they are usually only used for shorter journeys. A seemingly low mileage vehicle may have completed a lot of shorter journeys, which can lead to worn out brakes, door hinges, leather and carpets.

There are certain myths and stigmas attached to classic car ownership; however, we believe these assumptions are uncalled for, with no real evidence to back them up. In this post, we aim to dispel some of these niggling doubts, and hope to show you what makes classic cars so great – better than modern vehicles in many cases…
Driving a classic car can be perceived negatively – particularly when it comes to the environment. Environmentalists sometimes view classic cars as being gas guzzling planet destroyers, due to their poor fuel efficiency. In reality, salvaging a classic car is in fact an excellent example of recycling – maximising the use of something rather than just disposing of it.
Keeping an old motor running, rather than just replacing it at the nearest opportunity, is sustainable and limits the amount of waste in our scrapheaps.
Some prospective classic car owners are put off by the thought of their car’s value rapidly depreciating – especially if driven regularly. In some cases this may be true, as with the ‘flashier’ marques, such as Ferraris and Lamborghinis, which don’t fare that well off the racetrack – particularly on uneven road surfaces and when confronted with speed bumps. These cars are more of an investment than a usable vehicle.
This needn’t be the case, however. Vehicles labelled as ‘modern classics’ are more driveable, and can indeed prove excellent vehicles for modern, day-to-day life. Classic cars like the Jaguar XJS are versatile, practical and, best of all, fun to drive. They’re also proving excellent investments, as this article by Yahoo Autos recently pointed out.
Find out more about the XJS and its investment potential.
In some cases this can most certainly be the case, as shoddy workmanship will no doubt markedly decrease your vehicle’s value. Distasteful or bad quality restoration is likely to be frowned upon by those within the classic car community, who favour in keeping, high quality restoration.
At KWE we have many years’ experience restoring classic Jaguars while keeping the appearance and ride characteristics as factory-new and wholeheartedly believe that high quality re-engineering can actually increase your car’s value. We can also of course make further improvements – both cosmetic and mechanical – to the client’s requirements.
We have worked on a number of bespoke projects: Manual gearbox conversions, power enhancement, modernised engine management, custom sound systems, revised electronics and even wine racks for James May and making room for our client’s dog, Pops!
This is one of the biggest fears associated with classic car ownership, and puts doubt in the minds of many potential owners. Rust can indeed cause a lot of damage, and make your vehicle unfit to drive. With some TLC and expert engineering advice, rust can be avoided and kept at bay.
To ensure that you aren’t leaving the rusting of your classic car to chance, why not speak to the experts? KWE are experienced in preventing and remedying rust, and have developed techniques which make our cars last a lot longer than average. We know where to look for rust, and offer both cavity wax injection for box sections, and full under body sealant renewal.
We recommend repeating this inspection and proofing process every second year. This regime vastly reduces the chance of further rusting. If the customer specifies a bare metal re-spray it is then possible to inspect any previous topside problems and rectify them if necessary.
Read our post on rust prevention for more information.
Perceived rarity isn’t everything when it comes to classic cars. It’s not all about initial value, but rate of growth. The XJS is growing in esteem and sales value in leaps and bounds – more in percentage terms than Italian exotics. Cars dubbed ‘modern classics’ are reaching new heights, and proving affordable investments for those looking not only to achieve excellent returns, but also to enjoy their investment in real-life situations.
Highly desirable cars are not necessarily rare. The Jaguar XJS is a fine example of this, and as it becomes increasingly popular, its investment potential is growing also. Now’s the time to invest before prices sky rocket!
If well maintained, higher mileage classic cars are more likely to be reliable, simply because they are driven more regularly. Parts that may have been faulty have long since been replaced with new ones. Cars that have lower-mileage, on the other hand, may look good on paper, but in reality can be riddled with issues that haven’t been resolved.
A driven car is a car that has been known and understood by someone.
Winter can be a difficult time for any car owner, as the cold weather and icy conditions put an extra strain on the vehicle. And this links to the earlier point about rust, as salty roads speed up the dreaded rusting process. Again, this needn’t be the case, as with appropriate care and attention, your classic car can be just as comfortable in the winter months as any other modern vehicle. Check out our top tips for running your classic car in the winter.

You want to ensure your recently purchased classic car lives up to your high expectations. In order to get it up to scratch, you might be considering customisation or restoration work. You may be sceptical, however, as some in the classic car community frown upon such customisation, branding it sacrilegious to a car’s original philosophy.
So, should customisation be considered as part of a restoration plan at all? Or should you bite the bullet and accept the car for what it is, even if it doesn’t meet your requirements? This post examines whether customisation should be embraced or avoided altogether.
There’s always the risk when carrying out a customisation project that the work may not befit the quality of the original vehicle. Shoddy workmanship will depreciate value, and may even cause some major engineering problems in the long term.
A new trend, coined ‘restomodding’, draws from the advancements in automobile technology to enhance the performance, comfort and safety of the classic car. At KWE, we refer to this as ‘re-engineering’. We use modern parts and materials to bring longer life, safety and performance to classic cars. The result is a classic that can be used for daily driving, a holiday adventure or transcontinental blast in comfortable excitement.
This doesn’t mean that all ‘restomods’ fulfil the brief, as many would argue that they have been tastelessly restored, leaving some classic motoring enthusiasts wincing. If you’re not looking for a Pimp My Ride-style abomination, it’s probably best to seek expert advice.
KWE Cars prides itself on its ability to restore classic Jaguars back to ‘better than new’ quality. With many years’ engineering experience, we are firm believers in restoring with your needs in mind – and we make sure we complete all work to the highest standard.
When it comes to customisation, we believe that it comes part and parcel with classic car ownership; it’s all about making sure the car suits your way of life. We focus on improving performance and making the vehicle more practical and comfortable for modern life – all without ruining that classic car magic that enthusiasts crave.
Through carefully tailored and bespoke solutions, our interior and exterior customisations allow for an enhanced driving experience. Leaving no stone unturned, we can restore all aspects of your classic car, from new leather seats and alloy wheels to reconditioning the engine.
We’ve worked on some interesting cars over the years, taking into account our customers’ varied requirements. We believe this stands testament to our ‘can do’ attitude and expertise.
We recently finished the restoration of a 1988 V12 convertible XJS, complete with a special request from its owner. The client likes to take his dog, a black Labrador named Pops, out with him when he drives his XJS, so needed somewhere flat in the back for him to sit. We removed the convertible luggage box in the cabin and replaced it with a flat floor. Pops now sits in full wool-trimmed luxury!
Other bespoke customisations include personalised leather seats and alloy wheels, state-of-the-art sound systems, and a wine rack in the boot for James May and Oz Clarke’s BBC series.
KWE customers can design and commission their own alloy wheels, select that perfect shade for the paintwork, customise leather interiors, and so on – we do all this with the highest degree of skill, ensuring that the finished result befits your high expectations.
Driving a classic car should be a privilege, and a carefully planned restoration can enhance this experience further. A quality, high finish customisation will embrace and sympathise with the craftsmanship of the era, building upon this to further enhance the pleasure that comes from owning a classic car.

Many of our Jaguar XJS customers seek our advice on classic car insurance, and no wonder – it’s a rather different requirement from normal car insurance.
It’s important you consult a reputable broker who specialises in classic car insurance, in order to get the best possible cover for your classic car. We would recommend researching the following insurance companies, but there are, of course, other reputable brokers available:
We would highly recommend going for ‘Replacement Value’ insurance cover, in case of unexpected damage, such as a collision or accident as you drive your freshly-restored classic away from KWE! This helps to overcome issues relating to the ‘book’ value that insurers sometimes offer, which might be a tenth of what you’ve just spent.
The above insurers provide specialist advice, and really know their stuff when it comes to classic cars. While they might offer only a limited mileage policy (typically 6,000 miles per year), they should be fine with insuring the car for a more accurate replacement value. KWE can confirm the value of the works done for Insurers. In the end it is about establishing what it would cost to replace the car with one in similar condition. We take the view that substantial improvements such as an engine rebuild or bare-metal respray, or full suspension renewal would count at their cost value on top of the car’s intrinsic but non-restored market value. Items such as servicing, repairs and rust protection would not add to the replacement value.
So do inform the broker about the following if applicable:
The sort of things that would be excluded from your policy are as follows:
We recently completed work on a 1983 Jaguar XJ12 Series 3 Saloon. Prior to its full-scale makeover, this classic had been sitting in the sidelines at KWE for several years, awaiting a client to commission its restoration.
Last year, one of our existing customers enlisted our expertise to restore the model back to its former glory. The customer – a true XJ enthusiast – is already the proud owner of a KWE-restored 1991 XJS, featured on James May and Oz Clark’s BBC series, Oz and James’s Big Wine Adventure.
The body has been completely stripped and repainted in gloss black, with ‘biscuit’ Connolly hide throughout, full interior makeover, and new KWE suspension, making this classic a real head-turner.
