I've always wanted a Buick Riviera ... but never quite had the cajonies to buy one ... will never own one now - I just like the idea of owning it. Could be one of the boat-tail ones or the earlier ones - they just look superb from the front or back I think. No idea what they ride like - like a liner no doubt - but it's just the road presence.
Failing that, some fibreglass Ford special from the 1950s conceived on a beer mat or the back of a fag packet. Take your old Ford, rip the cycle wings off it - and install one of these here new fangled plastic bodies and it becomes a sportscar overnight. I just like the whole concept.
Failing that, an R107 Merc ala Bobby Ewing in Dallas, but that's hardly an unusual car, just a good one.
