I think you can do much better, for the money, with some decent mods on a mk1 mr2, granted that is used car and would need some mods, but it still would be alot cheaper.
But to my main point, where the hell are these twisties!?!? i live in the east bay and i can't find any except from oakland to san leandro, and near crow canyon, even so those ones suck compared to my favorite spot which is in italy, so kinda out of luck.
