At the top of the XJS section you'll find a FAQ/sticky thread with an XJS buyers guide that might answer some questions.

Immaculate cosmetic condition is a real "plus" as paint, leather, chrome etc are ungodly expensive to have redone

Low miles doesn't guarantee perfect mechanical condition, especially if the car sat unused for long periods of time.

If it was used somewhat regularly.....a few times a year, let's say....you should be OK. Assuming routine fluid changes and such, of course.

I suggest reading the buyer's guide and coming back with more specific questions.

XJSs are fantastic cars but they are quirky and need attnention. Even the best ones are not "drive it and forget it" cars. With care, though, you'll have a reliable Jag.

Repairs ARE expensive unless you're a DIY mechanic.

What Doug said. I'll add that the vehicle could be in need of deferred maintenance - rubber parts in particular will still age and crack.
