Jim Rome's 604 HP What?

Ok so Im listening to Jim Rome tell the corvette guy story the other day and he mentions he has a 604 HP car but not what it is. Whats he got?

I've heard him tell that story a few times but he never says what he has besides that it's foreign so maybe an Enzo or something? No idea, just a guess.

Mercedes SL 65 AMG has exactly 604hp. Bingo!
