Thanks for the response!I've had 2 C5s and 3 C6s. I still have my last C6 - 2013 427 Vert 60th Anny.
Each new generation offers better ride and handling than the previous.
The C6 offers a 6-speed automatic while the C5 has the 4-speed auto. Both can be had with a 6-speed manual (my choice).
Generally, buy the newest Vette you can afford and with the options you want.
