I had a 1989 JaguarSport XJRS V12 6 litre some years ago. It had a magnificent engine built into a British Leyland quality body. It rusted, the electrics (apparently 3 generations overlaid on each other) were appalling, and the interior trim wasn't so much built down to a price as cobbled together from random bits. The coil, a Magnetti Marelli item, was situated in the vee of the engine, where it failed regularly. I replaced it 3 times. I gave up eventually and sold it to a Jag racer who wanted the engine. It could have been such a great car - Clarkson was a fan in period, and I vividly remember the time when I finally got it fixed enough to drive it in anger. The acceleration was unbelievable for someone who had previously been driving a P6 3500 as a daily. I also had a 1977 XJC 4.2, unfortunately that was a very poor car as well. I don't think I'd ever buy another Jag.
