It all depends on the car. some of them come off lease some of them are totally screwed up. Just an FYI the auctions do a pretty good job checking out cars before they are sold. I was looking at an S4 which seemed great but when they looked at it they pulled it from the auction due to the engine being messed up. I drove another one and everything seemed good then the wiring was all screwed up and it got pulled. If you like and trust your nieghbor i dont see any problem with an auction car. get a carfax and make sure it doesnt have a salvaged title. (no one likes those) most dealers if they have a car for over 2.5 months they will try and sell it at the auction to just get rid of it. I drive tons of cars to the auctions every week.
