It's been a while since I played, but I think my favorite was one of the carbon fiber cars, probably the stunt boost one? It might have been the one that was originally stunt boost but converted to speed boost for the carbon fiber version. I got every car in that game (101% woo) so they all kind of blend together a bit.



The Uberschall was really cool with the sonic boom effect though, just hell to keep on the road for more than a few burnouts.
