The method by which Goodwill sells the used cars that are donated to them varies by location. Some locations hold auto auctions periodically, while others have a sales lot that prospective buyers can visit.
Local Goodwill branches that conduct auto auctions may list their current car inventory and the dates of upcoming auctions on their web site. Trucks, boats and RVs are also sometimes sold at these auctions.
Locations that have auto sales lots are usually open to the public during normal business hours. They may also have a web site that lists their current inventory along with any mechanical issues the vehicle may have.
