I guess it's each to his own, but I always enjoyed using the sample 04 body (1 of the Cerberas) on some hybrids. Even though it disappears in replays, I guess I like the look in the garage. True that other than sample 01 the rest of them share the same parts, from the supra rz I think, but I still like the 04 body.
Yes it's 06 that freezes the game.
