Wanna go fast(er) around a track? -> C7 Z06
Wanna do long distance touring? -> Likely C7 Z06
Wanna more "pure" sports car sound -> C7 Z06
Wanna do ANYTHING else in a sporting fashion and be entertained from 0mph, 20mph, part throttle, full throttle, low/medium/high speed turns, incredible steering feel, incredible chassis feel, etc, for the rest of your life in the most engaging American street car ever made? -> Gen 5 Viper
It is really that simple. There was a guy on an Italian exotic forum, who said it best (talking about dct transmissions, awd, and performance traction management, and generally how speed-appliance newer cars are becoming), I paraphrase: "We all have moments of weakness when confronted with the latest car that has unbelievable performance, and so we go buy it and it is fun... for awhile, and then we realize the fun is really tied to insane road-driving, straight-line blasts, or track-only experiences, and we end up selling it and the cycle possibly begins anew..."
I just sold my C6 Z06 after putting 56,000 hard driven miles on it, and while I've never driven a car more brilliant at 9/10ths+ (even slightly better than the Gen V imho, and the Gen V is damn good), I don't miss the car at all outside of that extreme use-case. Once you get past the eye-popping straight-line and quite nice sound with an aftermarket exhaust, it isn't very engaging to drive in the guise of a street-car. You must be in full attack mode for it to really warm the soul (and it is a near religious experience at 10/10ths if you have the skill and balls), and so if it isn't your trackbeast then one day I bet you too will be selling with few regrets!
One of the most rewarding street cars I have owned in a 3-pedal E60 M5 (with aftermarket exhaust). It isn't particularly exceptional at any one thing, but once you drive that V10 powertrain the way it wants to be driven, it is one of the best experiences I have had from 0-8/10ths. This is from a porky 4,100 pound sedan! It falls down a bit at the extremes but who is driving a street car at extremes on a regular basis?
Listen to this advice and save yourself a lot of money: Buy the most engaging cars you can, the ones that never get old, the ones with tons of personality in as many possible modes of operation as possible, the ones that you can't stop thinking about and are constantly scheming for a reason to drive them again. Chase the latest, greatest, and fastest things at your own peril. It will lead you to a dark, dark place (that leads to what I call GTR / 991 Turbo syndrome...).
Frankly I hope the magazine-racers move on from the Gen V and leave it be to the enthusiasts who are wise enough to know what they have stumbled upon, and how rare such a currently produced car will be in the very near future...
