Just at 33,5k miles in my 2005 CTS, and still enjoying the heck out of it. It is quick, corners well, and fairly economical to drive. Total cost is around $30-40/month more than a Honda Accord EX, which is much less car.

I'm watching the new cars arrive, but my Wife will need a new car this year. We have a new driver in the house starting in Jan, then are looking at college costs starting again in a couple years for our son, so my next car may be a lightly used older model (hey, like I have NOW!).
