Nice car, and a nice price.
Issues with the Jaguar you've found:
1. Nikasil cylinder liners. These were in some Jaguar V8 engines up until
the 2000 model year. (see VIN numbers in the link below).High sulfur content
fuels erodes liners, and eventually the engine loses all compression and
simply won't start.
2. Timing chain tensioners. In Jaguar V8 engines up to the 2003 model year,
Jaguar used plastic upper tensioners, which can crack, leading to chain jump
and potential valve damage.
3. Like timing chain tensioners, Jaguar used plastic impellers in the water
pumps in the V8. These eventually fail.
Get a blow by test to determine whether the car you are looking at is
suffering as a result of Nikasil. If not, it is likely OK -- there is far
less sulfur in fuels these days.
As for the tensioners and water pump, they will have to be replaced for sure
(upgraded metal parts are now available), and you should get quotes on the
work and deduct it from the asking price. Cost for this work in Canada (all
chains, upper and lower tensioners and guides and the water pump) is about
$2300 -- about 1000 pounds.
