 I regret to say that this was the worst Mercedes I have ever owned. It seemed that something went wrong with it every other week. The digital read-outs on main display failed causing to lose the ability to use particular options, HVAC system completely failed and needed total replacement, window regulator failures, side mirror motor failures, seat heater failures, seat adjustment motor failure, trunk release failure, fluid leaks, engine mounts needed replacement (@ 60K miles!), and many more malfunctions. Despite this being Mercedes, nobody should be experiencing this many problems with a car costing this much. It is by far the worst car I have ever owned.
