Judging by the problems from Jags to BM's on that site, you might get some grief but nothing remains 100% reliable forever. Think of it as a feature, not a fault. One of the guys I work with has twin turbo derv which has been sat at the Dealership for some time as they can't work out the electrical problem connected with the twin turbos.
I like the shape and spec of nearly all the Jag range but something in the back of my mind said stick to BM's. Might be worth trying to blag your nearest garage for a weekend demo test drive to see what you think?
