I just bought a 2003 ML500 with 41,000 miles. I currently have 49,800 miles. The car is still under teh bumper to bumper factory warranty. The car runs great and I have had no problems. The only I had to get fixed were the driver-side memory seat cover, a crack in the sunroof switch and the radio going up and down. Does anybody recoomend getting teh extended warranty if so what does it cover? What type of problems can i expect to happen to the car after reaching 50,000 miles.
