 Purchased this as a Starmarked vehicle with extended warranty. Have had more problems and needed repairs for a vehicle that cost as much as this did. Brakes have a squeal that our current dealer has checked at least 3 times and claim that nothing is wrong. Had the glue on the doors melt onto the windows. Now have multiple broken gadgets. Windshield wiper fluid tubes are rotten. I don't open the sunroof anymore because there is a suspicious cracking noise when it opens. The front seals at the windows are degrading, leaking water with rainshowers. Time to get a new car. Never again a Mercedes.
