I have had my CLS 550 for a little over a month now and I absolutely love it. First time MB owner as well. Looked at some BMW before I decided on the CLS and am very happy with my purchase. My favorite thing right now (seem to find a new one every time I drive it) is the 382 hp. It's a pretty cool feeling knowing I can pretty much pass anyone at anytime. Look forward to being in the MB family for years to come.
