@Badgertits 3 time Corvette offender here: C5, C5Z, C6Z
I used to be about performance numbers, but nowadays, I have a slightly different objective: especially because capabilities have improved dramatically over the past couple decades, after a certain minimum performance level, for something less than a competitive race car, I find driving enjoyment > performance capability.
But I agree either > super great fit and finish, though I do have an appreciation for good seats. And I have an aversion to infotainment.
On the eurotrash vs murcan tangent, I had the C6Z ~5 years, owned the C6Z and the e90M simultaneously for a couple years. Compared with the M, the C6Z can unquestionably put down better track numbers, but unless it's warm, dry, I have good pavement, and a fresh set of tires on it, I had a ton of trouble putting down power at any legal speed. To the point where, when driving on the street, I found the M as fun or more fun for anything less than lose-your-license territory. YMMV; I think that where one drives (some states have a very different roads from other states) and how one drives makes a big difference.
That said, I really liked the engineering of the C6Z: CF fenders, CF + balsa floor panels, Al frame, Ti rods, Ti intake valves (and exhaust after I sent my heads off to WCCH ahead of breaking an exhaust valve), a very light weight and space efficient design in the LS series of engines, huge brakes, etc. etc. I wouldn't mind converting a C6Z to a serious track toy sometime in the future, though there's a larger chance I'll build up a Cayman.
BTW, IMO the C6Z checks identical aesthetic boxes as do the Rap and M3.
