Purchased my new 05 E-55 after having owned 3 problem free Porsche 996's. Initially I loved the car but quickly lost the attraction after the engine stopped running on a very busy local highway at rush hour. Car was towed in and repaired (loose wiring harness). Two weeks later my interior insulation filled with fuel due to problem with the fuel pumps. Left rear shock leaked and car would settle over the wheel when parked for a few days. Brakes squealed like a Yugo. The squealing brakes problem never stopped after several visits to MB service. Lost confidence in the product and sold the car. Done with MB. Without question the worst vehicle I have ever owned.
