What affects its junk value

  • Age: at 23 years old, most of a 2003 SL-Class's value comes from reusable parts and scrap metal, not resale.
  • Weight: as a two-seat sports car, it weighs less than a truck or SUV, so its value leans more on parts than on scrap weight. See how scrap prices by weight work.
  • Catalytic converter: like all gas and diesel cars, it has a catalytic converter containing precious metals, one of the most valuable parts on a junk car. An offer assumes it's still in place. More on catalytic converters.
  • Recalls: NHTSA lists 4 recalls for the 2003 SL-Class. Open recalls don't stop you from selling or junking it.
  • Known problems: owners reported the most issues with the suspension, typically around 64,000 miles. If that's what failed on yours, it can still be sold as-is.

Risk: In the event of a vehicle crash, the electrical fuel pump may not receive a crash signal that is required for the fuel pump to disconnect and prevent future fuel delivery as designed.

Service Brakes, HydraulicApr 2005 · NHTSA campaign 05V133000

On certain vehicles, the sensotronic brake control (sbc) system may prematurely shift to the hydraulic back-up function mode, due to deterioration of the wiring harness connection, or due to premature failure of the hydraulic pump.

Risk: In the hydraulic back-up mode, the driver has braking power sufficient to stop the vehicle, although greater brake pedal pressure is required and the brake pedal travel will be noticeably longer.

Service Brakes, HydraulicJun 2004 · NHTSA campaign 04V296000

On certain vehicles, the electronic monitoring system of the sensotronic brake control (sbc) is designed to monitor the pressure gradient within the high pressure line of the brake system. If an unacceptable pressure gradient is detected, the system will switch, as it is designed to do, into the hydraulic function mode.

Risk: If vehicles are not routinely serviced and have extremely high mileage combined with a high number of brake actuations, or a high brake actuation frequency, the pump motor of the sbc may run out of permissible tolerances, thereby triggering
