Specs, fuel cost and emissions from the EPA's fueleconomy.gov data; weights from NHTSA crash-test records. Your car's exact equipment may differ.

What affects its junk value

  • Age: at 8 years old, a 2018 S6 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: NHTSA's crash-test 2018 S6 weighed 3,951 lb at curb weight. Scrap value is largely priced by weight, so this is a good starting point. 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 1 recall for the 2018 S6. Open recalls don't stop you from selling or junking it.
  • Known problems: owners reported the most issues with the steering. If that's what failed on yours, it can still be sold as-is.
