I have owned a 1999 XJR for 2 year now, and have had no problems with it at all. The previous owner had the dealer perform all the maintenance, and just 4 months prior to my purchase, the cam chain and tensioners were replaced. He also replaced all wheels and tires, as the old wheels were flaking. I purchased the car for less than all the repairs and wheels cost!
The car now has 121k on it, and is in beautiful condition. I get comments all the time on how great the car looks; some say it looks new, and are surprised to find out it is a 99.
I love the power in this car; nothing in my area can touch it.
I read in the above comments about replacing the supercharger oil, not sure if mine was done, went to Ford dealer and they want $25 for 4oz bottle; it will take 2, the GM dealer wanted 17.50 for same size, I got one on line for 19.99, and it is a 8oz, and comes with syringe to pull out old fluid also. I also wanted to replace the trans fluid; talked to the dealer, and was told if it is not leaking, don't do anything -- comments?
I did hit a deer last winter with the car, and my insurance totaled the car, I bought it back for $779.00. I then purchased a 2001 that had a bad motor, and took the parts off and the body shop charged $2000.00 for repairs and paint. The car is just getting better. The 2001 has Michelin Pilot A/S tires that have between 7 or 8/32's, so they almost paid for the car. I also took the trans out (the car only had 55k on it) so if and when mine goes out, I'll have a replacement.
I would recommend this car to anyone who wants style, comfort and power at an amazing low cost.

The same thing happened to mine, and by turning it off and then on again the next day or a couple of hours later, everything would be fine for weeks... sometimes months.
The car started doing it more often, with the end result being a diagnosis that it needs a new PCM. The whole car has been scanned with no problems found, except for the failed PCM.

For the last year, I've been seriously considering an E39 ///M5 to replace my wrecked E36 ///M3.
I've looked at 3 2004 Jags: XJ8, XJR, XJR. There's a nice '04 XJR for sale with 115K for $12900. No history.
These stories have just about convinced me to go for the rather dull-looking, but bullet-proof M5. I'd much rather replace a clutch now and then, than deal with the Jag slushbox. Too bad... the XJ is a great looking car.
