2010 Mercedes-Benz E-Class E350 4dr Sedan (3.5L 6cyl 7A)
Bought car and afterward had knee surgery. Only 250 mi I've put on car, but, garage door opening buttons on rear view mirror receded and unit had to be replaced. Rained on way to dealer and had clicking/sticking noise from wipers; fix - they had been installed backwards. Have replaced air filters w/K&N; going on long trip and soon and hope to see improvement on gas mileage.
