My idle rpm's at a red light run about 500. Is it normal? My other non MB cars run 700-800. Also, probably related question, I can take my foot off the brake at a red light and the car (CLK) stays and does not move, whilst my other cars always try to go, even on the incline. I also noticed that if I judge the distance to the red light correctly and take my foot off the gas, my MB will coast to the red light and stop without me using brake at all.
