In itself, I have no problem with a diesel car. My truck is diesel, we nearly bought a 118d last year, they're fine for what they do.
With all due respect to Dave and his Jag, which is a very fine machine and is certainly no slouch, for me personally I would never want one as my fun car. They can be enjoyable in their own way, but they can never touch a good petrol engined car in terms of enjoyment.
All IMHO, YMMV, etc.
