Hi Tony. While I'm not going to get nasty as some of the posters here, they are correct that this car is a convertible, and not a cabriolet. I own an '88 Jag XJ-SC (C = cabriolet) which is the last year the cabriolets were produced. It's still a beautiful car, just not a cabriolet.
Ken, you may not be wrong, but you certainly "ain't right"! =)
