What affects its junk value
- Age: at 8 years old, a 2018 CT6 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 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.
- Known problems: owners reported the most issues with the engine, typically around 22,000 miles. If that's what failed on yours, it can still be sold as-is.
