My current newer cars:
2010 Camaro SS
2010 Audi S5
2009 Corvette Z06
2009 CTS-V
2006 Viper coupe
I like the CTS-V the most out of all of them. It does everything well, without compromise. I'd say it is comparable in fun-factor to driving the Z06. Not as fast, but just as fun. Mine is an automatic, and I usually hate automatic trans cars, but not the one in the V. The car is perfect with the auto trans, as it stays in full boost all the way through the gears. The Caddy has humbled too many cars to mention, which is a huge LOL most of the time.
Here is mine, lowered on D3 springs and riding on HRE 20" monoblock wheels.
