Hey, i test drove today a merc C220 1995 and it was pretty impressive. Since im not experienced in this car, i have couple of questions. When the engine is on and its on Park, the RPM tends to play a bit up and down, and when u press the GAS u hear a "FSSSSS" sound. Its like air is escaping from somewhere. Second i wanna know when youchange from P to D or R does the engine move a bit???? Im looking forward to know if this is normal since im interested in buying this car. I would like some help and advise.
Thank you
