What affects its junk value

  • Age: at 8 years old, a 2018 S-Class is newer than most junk cars, so working parts like the engine, transmission and body panels are in demand from rebuilders and parts buyers.
  • Weight: as a small 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 11 recalls for the 2018 S-Class. Open recalls don't stop you from selling or junking it.
  • Known problems: owners reported the most issues with the service brakes, typically around 30,000 miles. If that's what failed on yours, it can still be sold as-is.
