Recently drove my CTS 3.6 from Monterey to Big Sur and back on the Pacific Coast Highway. I drove at the limit up and down the hills and hairpin curves never using the brakes - just the sport shift! It was as if the car was on rails! I own a Mercedes and have owned a VW and a BMW. It handles just as well these do - but is more comfortable. It glides in and out of traffic with terrifc acceleration and with smooth, effortless shifting. GM doesn't know how good a car they have. Interior could be a little sexier.
Handling, comfort, acceleration, OnStar and XM radio.
