Almost bought a '99 XJR myself. Couldnt believe a small-block V8 (4.4L) motor could perform like that - supercharger or not -- simply unbelievable. Could have had one with 16K miles for $29K - a year and a half ago. Considering it went out the door for around 70K, that was some kind of depreciation hit. That, and the reported cam shaft difficulties reported on Jaguar forums like this made me hold off - but, whoa, what a beautiful car. Probably the last of the great Jag sedans!
