i dont think that using an rx-8 body for the rx-7 is acceptable...the rx-7 when in it first debut in 1993 in the states was totally awesome from the second gen rx-7..the third gen was a hit that mazda had designed as its own custom built design..the 3rd gen was not based on a porsche as was the 1st gen or any other car. rumors about the supra being based on a ferrari was found to be true and i thought it was revolting. the next gen rx-7 should have its own platform without any traces of an rx-8..it should be the sickest and wickedest looking and performing ride on the face of this earth and mazda can do it! whether the engine is a renesis or a 20b, that doesnt concern me, as long as it is reliable, fast as hell, and (up to its reputation) a total eye catcher i myself will put down 30 g or more for it.
