Just saw this video
Everything I've read suggests the Shelby Daytona coupe was the inspiration for the 2nd gen coupe while the Shelby Cobra was the inspiration for the first gen roadster. This stands to reason given how much the 2nd gen coupe resembles the Daytona coupe.That's the Vipers inspiration.
YES!.Gearing matters too, I have no interest in a Porsche Boxster that does 88mph at redline in second gear, my 4C is doing about 115 at redline in 4th.
