I think Mark's got the pants beat off of everyone here.
I've ridden in a number of fast cars and actually managed to drive a few around the block, but the fastest streeet car I'd say I've been in was an '02 SC'd C5 coupe. The torque response was just viscious and it never ended in any gear (the driver didn't run out 6th, so I couldn't talk to it). It made my C5 feel like a damn sloth...
I'd dearly love to take a ride in some of these 900-1000HP FI'd Vipers that you occasionally see mention of in car rags. I'm not a big fan of Vipers, but there's no denying what that V-10 pushrod is capable of.
