One of my good friends has a '10 CTS-V sedan. His is an auto (which I wouldn't get, personally) but I personally think this is a great car. Last September we took a road trip (~14hrs both ways) to Warsaw, IN to go to www.wait4meperformance.com
and he had some cool stuff done to the car. For the amount that some of us spend on an exhaust and CF diffuser, he had porting, heads, and other things to yield him 640 rwhp. The car is an absolute beast. He jokes that he'd beat me until the first corner if we were racing, but the thing handles great, too. It's an american car for sure, but I have some respect for it. Remember that the guy that did our E60 M5 developed the CTS-V and he wanted to build a car that would beat our beloved bimmers. Does the CTS-V not still hold the nurburgring record for a sedan?
We are going to do a photoshoot together this summer so I'll be sure to link some pics to this thread if you guys are interested.
