I PURCHASE MY 2003 MERCEDES FROM CARMAX IN 2 YEARS AGO. IT HAD 45,000 MILES WHEN I PURCHASED IT. FROM THE TIME I PURCHASE THIS CAR I HAD TO REPLACE THE SUNROOF MOTOR, REPLACE THE SHOCKS, REPLACE THE TRUCK LOCK, REPLACE THE FUEL TANK, AND I HAD SOME TRANSMISSION WORK DONE. MY BIGGEST PROBLEM IS HAVING TO REPLACE THE LOW BEAM LIGHTS EVERY 6 MONTHS. I SUSPECT THERE IS AN ELECTRICAL PROBLEM, BUT CANNOT COMPLETELY PROVE IT WITH THE MANUFACTURER. WITH 1 YEAR, I HAD TO REPLACE THE BULBS 3 TIMES. I HAD TO REPLACE THE FRONT LOW BEAM BULBS AND THE BRAKE LIGHTS. THIS IS SURPRISING SINCE THIS CAR (UNDER MY OWNERSHIP) HAS NEVER BEEN IN AN ACCIDENT. I AM SO DISAPPOINTED I PURCHASED THIS CAR! *TR
