I’m looking to buy a used car and have been told good deals can be found at auctions. I’m just worried about buying a lemon that looks good on the outside and a POS later. Any experiences would be helpful. Any fees, deposits etc?

The one I went to let you look over the cars and most of them they would drive under it’s own power into the auction block.
So go early and look over the cars you want to bid on, if you find a good one, most likely someone else looked at it too.
