Car was repossessed sent to auction. Paid off balance prior to being sold. Picked up car at auction. Drove off auction lot car stalled. Lifted hood someone changed the entire engine Whats next?

I work for a vehicle finance company & my job is to order up cars for repossession, set up repo agents to pick up vehicles and to take care of auto auction issues when vehicles are stored at an auction awaiting sale, or have been sold. Well first off you need to call the auction, the repo agent (the person who picked up your vehicle or company) and then also your bank or finance company that the loan was through. Discuss the issue with them & see what can be done or what they want you to do. I have to say that this is a very weird thing to hear about. It is not in the auctions best interest, the repo agent or the financial institution to do anything to a vehicle, and never have I heard of any such thing. Think about it, the auction gets the same amount if the car sells or if it just sits there, the repo agent has done his job so he gets his money, and the financial institution wants their money & wants you to pay for the vehicle and if the car isn't running you may not be able to do that with the cost of repairs and such. I have to say I find it very unlikely that the auction or anyone else that had access to your vehicle would do any such thing......
