Beautiful. I love them. The one problem I don't have as a couple others have stated is the overheating issue, as I always put the invincible radiator in the vehicles. I'm not into the realistic engine temps and all that, just enjoy the speed and crashing.
Pretty good! enjoyable, I'd personally like the turbo rally engine too :3, one issue I found with the Bolide, is that the radiator can't handle the new engines and it overheats even when being driven sensibly.
