We purchased our car used from a Mercedes dealer, it has been in the shop 9 times in 8 months. Tail lamps melted, rear hatch locked shut, air vents all broke. Temperature controls were stuck on a temperature could not change. Plastic on seat rails has broken multiple times. Bad wheel bearing, rattled catalytic converter, broken latch over spare tire, misc trim pieces needed to be realigned. We loved the car initially but after 8 months of loaners for a week at a time in some cases we have vowed to never buy another Mercedes. We have had several Mercedes prior to this one and this car has been a major dissappointment. I would encourage anyone not to buy this car. Do your homework!
Car has long legs and cruises great on the highway.
Quality control really needs to be addressed. Mercedes has really dropped the ball. We have spoken with others who have had similar issues.
