Why wouldn’t the Z06 be compared to the GT-R? They’re sort of in the same price range (around $70k) when you don’t look at dealer markup.
The ZR1 is going to be a good chunk more expensive though. The V-Spec may be better than it, I wouldn’t be surprised, but it isn’t out yet so we’ll see shortly. The 'Vette is up for a redesign pretty shortly too, so that might bring it up a notch.
I don’t know why you guys have to hate on American cars so badly.
