*Let me make it known right now that I am not (in most circumstances) a Japanese sports car fan...
That said, I do think that there is indeed a market for the return of the Supra given the success of the 350Z/G35 Coupe, RX8, and S2000. But, if Toyota is going to do it they need to build a car that enthusiests will want to drive. That means they are going to have to limit the computer controls, take out the electronic nannies, and let the car be as wild as it needs to.
That said, they are going to have to have a wide variety of models, and the current state of Toyota may not allow that. To have a Supra be truely successful here in the US, they are going to have to target cars like the Mustang GT and upcomming Chevrolet Camaro to get the most sales possible. That means there are going to have to be some fast cars for right around $30K, and that might be hard for the Toyota bean-counters to work out.
...If Toyota is going to go with a V8 in a Supra, are they going to use a street version of teir JGTC V8? Or would they be smart enough to use the new 5.7L iFORCE V8 out of the 2007 Tundra?
Still, I would need a lot of convincing before I ever went to a Toyota dealer looking for a Supra. With cars like the Camaro, Mustang, GTO, Corvette, M3, C55, S4, etc all within the general price range of the Supra (taking consideration of inflation from a few years ago till now), all of the vehicles previously mentioned have distinct advantages over the Supra: Price, performance, and reputation...
