I've had a few XJ series III and II Jags. Sold this one last Spring back to the guy I bought it from to finance my race car purchase. That one hurt, very rare XJ6C in close to non restored show condition:
Ex has a newer 2000 XJ8. I think they can be great buys but hers has been a lemon. The only thing that saved us was it was still under warranty when most of the (*&^ happened. It's got 80k on it and the engine was replaced under warranty by the factory prior to 20k and my/our ownership, rear end, ABS controller, a bunch of other little stuff and she just recently dumped $6k into a dead tranny. Sucks dumping $6k into a car worth $8 to 10k. Just like anything else, PPI buy someone who knows them, maintenance history, etc.
