CorvetteSS,
I read your other post about the quality of the Z06. I owned many Japanese cars before, and owning all Americans now. I have to tell you that, if you look at the overall picture, the Z06 quality is not so bad at all. I do agree with you that GM used many cheap parts on the Z06, but if you really think about it. The invoice of the Z06 is only around $41,500. This is hell of a good deal for a car that can perform like the Z06. It's the dealer that's ripping us off.
I guess it's all based on personal expectations. If you have a chance to inspect the Viper, you'll feel much better about the Z06. Of course, I do agree with you that GM can do much better, but then they may charge us more too. Just think about the cost of labor here in the US. They have to pay a person anywhere from $18-$25/hr just to stand there and slap on couple bolts.
Yes the Supra, the 300ZX, and the RX-7 had better interior qualities, but where are they all now??? If I have to make a list of all the minor things that GM can improve on the Z06, it's probably about 10 pages. But, if I own a Supra, it's probably the same....
I have to agree with you 100% on the performance. There's nothing that cost +- $10,000 can come close to the Z06's performance. So, keep on enjoying that nice looking SS you have......
