When building a race car it would be better to buy a flood car instead. The law states any car that stands in water up to the axels is totalled. Usually these cars have wet carpets etc etc, which you'll will be pulling out anyway. Salvage auctions are everywhere, need to find someone that goes and pay him a fee to pick one up for you. 944's will be hard to find, BMW 325 are dime a dozen. Good luck and remember, its always easier and cheaper to buy a race car than to build, find an older gentlemen that has cruising around the track for a few years..they're out there.
