Went to the Auction in Nashville yesterday and stayed with my plan on investing. I look for cars that may need a few minor repairs for those on Craigslist looking for a project car. One I bought was a 1998 Lincoln Navigator. 
I paid $650 after fees $765. I drove it back from Nashville. Some people are in this business to satisfy their ego. Others are in it for the money. Neither one is wrong. It's just what you feel your calling is.
