For one, the Supra will be a coupe and the Z4/Z5 are roadsters. Supra will be for true drivers and Z4/Z5 for hairdressors :) Kidding on the last part but the Supra should end up being the bigger performer if you look at the heritage and market that the two cars have had traditionally.
Ford got people's attention yesterday for sure. As a rule I hate domestics but Ford and Chevy have been impressin lately with their Corvette, Camaro and Mustang offerings -- C7, Z/28 and GT350. And the one achiles heel of these cars - their quality - is so much better than before and not...
I could see that since this car should have less technology but more performance and exotic materials. But it better have more impresive performence because the RC-F doesn't have much buzz at all from some not so impressive reviews.
