The current Mustang doesn't appear to be much of a slouch, either. You have a point, but Cobras and GT40s are unobtainium and were rarer than Corvettes. A Corvette has never been unobtainium, relative. And there are a whole lot of those floating around, expensive or otherwise. A Thunderbird that evolved over time to be a GT40 or even something else that wasn't a bloat-mobile and that stayed in production as continuously as Corvettes have been would have been great. I don't see Cobras or GT40s as what it would have become. Who knows. It didn't happen.
