What affects its junk value

  • Age: at 18 years old, most of a 2008 STS's value comes from reusable parts and scrap metal, not resale.
  • Weight: as a midsize 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 1 recall for the 2008 STS. Open recalls don't stop you from selling or junking it.
  • Known problems: owners reported the most issues with the air bags, typically around 80,000 miles. If that's what failed on yours, it can still be sold as-is.
