 Bought this car new in 2006. Was torn between the 650 BMW and the CLS500. Both seemed to purr but thought I would go for the lesser horsepower but try  for the Mercedes badge. Test drove each for a weekend, and found the BMW to be more appealing, faster, and over all a better head turner, but thought the MB was a better buy. Let's just say I had the Mercedes for 2 months and traded it for the BMW 650. The MB sqeaked, knobs cracked, just poor quaility I missed all this at the begining during my test drives. I guess if I wanted a Chrysler product, I should have bought a Chrysler. Never again. I learned my lesson on this one. Maybe once they stop sharing parts on $20,000 Crossfires, I may be back
