Let us know what you think, or if you have questions. We're a helpful bunch, as long as you aren't planning on adding chrome pillars or 20's.
Also, read up at www.cadillacfaq.com under CTS-V for a list of things to look for and common issues. Becoming a supporting member of this forum is a great investment to make sure that the bandwidth we suck by helping each other out gets paid for. I'd also recommend tossing Reed, the guy who runs the cadillacfaq web site a few bones, as it holds a wealth of pictures and info for you to use once you get your car.
