Where do you live? There is a guy here in Tallahassee that buys and sells cars from the auction in Orlando. Most are off-lease or rental. Charges a flat processing fee.
If you are willing to let him grab one with a bad bumper or ding (not anything that would harm the motor or frame), he will have his guy fix it and you can save some serious cash.
I got a 2014 van to haul my camper and to use for the grand kids. I was "right side up" with my insurance company. I paid $21k something and my insurance company valued it at $27K.
