Just bought an SL 500 and noticed that there is a slight "clunk" coming from the driveline when I decelerate, just before coming to a stop. I asked the mechanic about this when I had the car cheched out before I bought it and he said that many SL's do that. I'm not sure I believe him. Either way, the car is under warranty for the next 3yr/36K, but I'm wondering if I should take it into MB for their opinion. Anyone elses SL do this?
