You can find some information online, on government websites which will let you search your area for a particular vehicle. These sites are not limited to cars, either. You can find SUVs, trucks and motorcycles on many of them too. Doing a ZIP code search and choosing a specific model will show you all the vehicles within a certain distance from you. Police specific auctions can be found by other websites like gov-auctions, which tells you when and where the local auctions will take place.
The goods you buy from government auctions are “as is.” Look on the “Terms and Conditions” page before bidding to understand the process. A typical auction page states, for example, that the auction site doesn’t guarantee the quality of the product in any way. Once you bid, you enter a legally binding contract, and you need to follow through with your bid.
