Because of how rare DeLorean cars are, it's worth checking eBay, which shows vehicles from across the world. Since Cars.com and other popular interfaces don't list DeLorean vehicles, it might be worth checking Craigslist.
The DeLorean Motor Company went bankrupt in 1982 and produced only 9,000 cars in 1981 and 1982. However, the release of Back to the Future, which featured a DeLorean-based time machine, in 1985 spurred interest in the vehicle and led to its popularity. The Back to the Future website estimates that only 6,000 DeLoreans are still on the road, but people interested in experiencing a DeLorean firsthand can visit the DeLorean Museum in Houston, Texas.
