I love the way the original GTS looked. Those cars just screamed speed... however, I've NEVER mistaken a Vette for a Miata in my side mirror before. Happened to me with a Viper once, true story. Was a similar dark green that the first generation Miatas had... felt like a tard once it passed me, but still. A 100k car should NOT be able to be mistaken by an enthusiast for something MUCH cheaper...
That all aside, Vette's just sound better. Never thought my feelings on this subject would be so one-sided until now, but Vipers, to me, have always sounded a lot like modified Audi 5-cylinder cars. Odd, to say the least. Last, I got to drive a C5 (would own it still had I been approved for the loan), and it was an absolute blast. Stock condition, handles 99% as good as a Miata, but goes like stink out of the corners, even if you're not revving the thing like crazy. I still have that drive burned brightly into memory.
Side note: Viper has been around for TWENTY YEARS NOW. I mean, it's one thing to say the Vette will be SIXTY next (model) year, but I still remember the original Viper coming out...
