I read an article on the possible 2004 (lol) or 2005 Supra design at Suprastore.com, and it hit me. The deaht of the Supra and so many otheres weren't only because of the decline in popularity in the cars, but their engines. Lots of the supercars of Japan used TTs.
Mitsubishi 3000GT:3.0 twinturbo V6 - ended production *1998.*(I think)
Nissan R34 GT-R: 2.6 twinturbo I6 - ended production 2000.
Toyota Supra Turbo: 3.0 twinturbo I6 - ended production 1998.
Nissan 300 ZX: 3.0 twinturbo V6 - ended production 1996.
Aparently the new Nissan 350Z (among many others) is N/A to have lower production costs and be more affordable, rather than go for a complicated twin turbo set-up because that is what really killed off the cars listed above. Their engines were so expensive and complicated to produce, that as time went on, the cars' prices only kept going up.
