How do these auctions work?

I am curious. I don't know anyone who has did an auction on a vehicle before. Have you ever gotten one and turned it over for a good profit?

I've bought a few vehicles and doubled/tripled my money on them all. Buying a vehicle can be risky, heck you don't even know if the engine is there until you own it. I usually try to get inside information from the facility manager. I bought an RV last year and the facility manager told me the owner drove it in about 3 months earlier, so at least I knew it ran before I bought it.
