the reason i believe that supras are expensive is because of the Fast and Furious movies and because they are more rare. i read somewhere that the number of 300zx produced outnumbered the supra, rx7,3000gt, nsx combined. id go with the 300zxTT. i recently had a NA and got a TT. i am very satisfied with the discsion. from what i hear, the 300zx are alot more fun to drive than the supra and the supra has alot of turbo lag. alot of supras with 600hp-800hp run 11's. Theres alot of 300zx's with stock turbo's that run that.
