Welcome to the forum. There ae probably lots of opinions on this, but for my money, the XJ6 sedands with the 4.2L Six are great cars! If you find a Jag (any Jag) that you are seriously interested in, it would be worth a few bucks to have it checked out by a competent mechanic. Jags, especially the newer ones (after the 80's) are not any less reliable than any other car, but in some cases maintenance can be a bit more. That's why its a good idea to get it check out first. Just a little insurance.
