only an 81 survivor would technically cost that much, and then only if you got the ORIGINAL BTF modded version (AKA the Hero Car from back to the Future, signed by the cast, no less). thing is, according to the little bit of GT4 paperwork (go ahead and read up on the cars, occasionally. i'm one of the few people who asked for the history paperwork back), the ones you won in 4, and that were ported to 5, are tunerversions. they replaced the bad hydraulics and the underpowered flat with something from (by the feel of it) Porsche. that's why they're "s2"
