Bad
Painted front bumper easy to scratch.
No means of checking 5-speed ZF autobox oil level or refilling it. Jaguar says 'sealed for life', but no oil changes could mean a 'life' of just 10 years.
No manual option.
Whine of Eaton supercharger of XJR8 can become irritating, but you only hear it when you boot the car heavily.
Nickasil bore liner sulphur erosion problem with pre-2000 model year Jaguar V8s. 1996s, 1997s, 1998s and 1999s could all have residual damage from before mid 2000 when sulphur content of UK petrol was reduced. (Definitely OK from from September 2000 build, or if fitted with a post Sept 2000 build replacement engine as these have cast iron bore liners).
Reports of tensioner problems leading to timing chain failures.
Front wishbone bushes can go after only about 20K miles causing steering problems, unven tyre wear and, if left unattended, possible suspension damage. Cost to replace can be £700. Jaguar's extended warranty does not cover this, but Warranty Direct's does.

Watch
Desirable to have a full Jaguar dealer service history and must be immaculate to command top money.
If the engine feels lumpy, it's a sign of serious engine problems.

Reports of tensioner problems leading to timing chain failures. Terminal if the secondary tensioners break and throw the chain more than two sprockets. The early X308s had quite a few known weaknesses: tensioners, water pump, gearbox that were sorted out after a few years.
Don't buy a 97 - 99 XJ8 VIN from 812256 to 878717 inclusive unless it has had a replacement engine, indicated by a special tag on the nearside of the engine block. Beware of rattles from timing chain as tensioner could be about to let go. Plastic tensioners were later replaced by steel tensioners which can be fitted to earlier cars.
Rear dampers prone to failure, particularly with CATS suspension.
18-10-2014: Where fitted, rear air suspension can be prone to failure.
