It just doesn't do it for me. I find the 'Vette has the Skyline's grunt and much better handling, and the RX-7 has the precision and finesse that the other three cars all lack.
I tried all 4 of those cars in a budget-build competition at Apricot Hill. At nearly full build, the RX-7 was the best of that group, with the 'Vette a close second, but somewhat harder to drive. The Supra was capable of astonishing speeds but mustered lousy lap times because it couldn't handle its own power. The Skyline was a little more stable than the Supra, but only a little quicker around the course. Neither of them were in the same league as the 'Vette and the RX-7, by several seconds/lap.
