I can find very little to complain about since it is a fantastic car. The audio system is good except for difficulty arranging music on the hard drive. Unless you can move the front passenger seat forward or lay it back the headrest creates a large blindspot. I have had irritating check engine lights caused by emission sensors of different systems. Most recently a module of some sort failed leaving steering wheel controls cruise, radio, paddle shifter inoperable. It was an expensive and time consuming repair.
I was just surprised with a new 2012 Cadillac CTS-V sedan from my wife. The car is stunning! I have owned several luxury and performance automobiles such as Porsches, Corvettes, Infiniti, Mercedes-Benz, Jaguar and have driven many others. The CTS-V and the other autos mentioned above are cars that the average person will never own, let alone drive in their lifetime. If you are lucky to own one of these automobiles consider yourself lucky and blessed. The CTS-V is simply the "Best Bang for the Buck"...period. You can find very few luxury-performance sedans that are faster, such as the Porsche Panamera Turbo(S) but you have to pay a huge premium for minimal performance gains.
556 HP, 550 lbs of torgue Engine...Enough said!
Blind Spot Alert for the sedan, and folding mirrors should be standard for this level of automobile price point.
Other than these few missing features, the car is blazing fast, handles like its on rails, is confortable, and looks that set you apart from the other generic "camry-deseased" autos.
Plus you can "justify" in your mind the 70k because its a top safety rated vehicle and you bought it to keep your family safe...yeah thats it, not the 3.9, 0-60 times-LOL!
One last thing, close to $2000 for the sticky Michelins when its time for tire replacements, but you already probably know that if you are looking at a car with this performance.
pay to play! Smoke em' if you got em
