I got the upper motor mount on my 2000 SL1 replaced today. The car had been\nvibrating like a Ford Pinto at lower RPMs. 88K miles on the odometer.\n\nIt took around an hour and was 5. I started the engine after getting it\nback and was very surprised how quiet the car was. It drove like a new car\nand the transmission felt tighter upon shifting. No more vibration and\nsoooooo much quieter when idling in traffic.\n\nThe service advisor suggested my brakes need bleeding and the radiator needs\nflushing for the next visit.
