I love my CTS-V. It is comfortable to drive and fun to drive HARD into turns. It has perfect balance. The only problem is paint rubbing off of the radio knobs and a rear end bearing failure. It has lots of wheel hop on a hard standing start, especially on wet pavement. I want a new '07 or '08 because of the 100,000 mile warranty. I plan to buy another one as soon this one's goes out of warranty..
The power and handling are as good as the Corvettes I have owned over the years, but cops don't look at you as hard. It has great styling and a good GPS system that will also play DVDs through the great Bose sound system.
Fix the rear end hop, which whiles out the rear end bearings. A Hurst shifter would be nice.
