Bought it used (2004), with 100K miles. First day the AC started to blow cold through the vents, but hot on the floor. Second day, the left rear door handle broke off, today the command console shut down completely. Rides well! Can't wait to see what tomorrow brings.

I just bought the 2004 S500 today. The test drive is excellent! Hope nothing will expose to me later! I have checked the Carfax report the 5 old owners seems to have starting problem! But when I cranked the car today it fired up instantly!
