1997 BMW M3: Buy or Avoid?

The 1997 BMW M3 is a legend, offering exhilarating performance and a truly engaging driving experience for its era. While inherently robust, its age and the demanding nature of a performance vehicle mean you MUST be prepared for proactive maintenance and the potential for moderate to major repairs, particularly if previous owners neglected it.

AIR BAGS:SIDE/WINDOW

VEHICLE DESCRIPTION: PASSENGER VEHICLES. THESE VEHICLES ARE BUILT WITH A SIDE AIR BAG SYSTEM CONSISTING OF DOOR-MOUNTED THORAX AIR BAGS (REAR DOOR AIR BAGS ARE OPTIONAL), A CENTRAL ELECTRONIC SENSOR AND DIAGNOSTIC SYSTEM, LEFT AND RIGHT SATELLITE IMPACT SENSORS, AND ASSOCIATED WIRING. THIS SYSTEM IS UNDULY SENSITIVE TO CERTAIN NON-CRASH IMPACTS, SUCH AS CONTACTING LARGE POTHOLES OR CURBS AT SUBSTANTIAL SPEED.

VEHICLE SPEED CONTROL

THE CRUISE CONTROL AND THROTTLE CABLES ARE ATTACHED TO THE SAME THROTTLE VALVE ACTUATING LEVER AT THE THROTTLE HOUSING. IT IS POSSIBLE THAT THE PLASTIC BUSHING ON EITHER CABLE COULD BREAK DUE TO ENVIRONMENTAL INFLUENCES COUPLED WITH VIBRATION. IF THE BUSHING BREAKS, THE OUTER CABLE HOUSING CAN SEPARATE FROM THE BUSHING. IN THIS CASE, DURING APPLICATION OF THE THROTTLE PEDAL WITHOUT CRUISE CONTROL BEING ENGAGED, THE OUTER TUBE COULD CATCH ON THE EDGE OF THE BROKEN BUSHING.
