Cool post... One minor correction: stock Gen II Vipers have gone 11.9 and 12.1-12.2 is pretty common.
Note that those C5's were modified autos. That's the only thing about my C5 that I really miss. In terms of outright performance, the NSX auto is pretty much a dog and can't even be modded effectively. True this is meaningless for 99.9% of buyers since manual is clearly the way to go, but as an auto driver, it's something that bugs me
