Aside from the basic "quirks" with a classic sports car, I have found no major problems with the vehicle.
If you are looking for speed, this is your car. It does 0-100 in 10 seconds and doesn't even breath hard. Solid smooth ride. Seating is a little tight for long legged people. Stereo in mine is LAME! It would buy another one tomorrow, a real head-turner.
We need an "autobahn" here in Canada for our Jaguar XJSs.
