you can find a download to eksis chevy here, though it is not 100% complete.
I did download it, but it's not, well,
that good, if you turn too hard the car flips, there's a problem with painting the regular vehicle, and plus it's a Chevy. It's just not that good as it could be. Plus, I might just make the damn thing myself, If I get Blender to work again :P But I can't model for stuff XD
