MotorWeek FYI: Public Auto Auctions

[BrashersAA]

You can also check out AuctionPipeline - they're primarily dealer-only sales, but a handful of them have public sales as well.

This is a good primer for the public auctions. Charity sales, Salvation Army, Goodwill, there's all sorts of public auctions out there. Police and towing impound yards are also good if you want to buy a project, and occasionally get a running car. I've personally bought running driving cars for $60, $65, $90, and $275. Check with towing/storage facilities, wrecker services, and law enforcement in your area to find out where the sales are. For example, there's regular sales 7 days/wk in DFW.
