Ok the car is not clean title anymore i would explain to you like this. The car got hit really hard, which means the insurance company gave them money instead of fixing the car which equals to the car being total loss. After it went to the junkyard they probably did not sell anything so it went back to action. Auctions can change the title of the car by just writing this one paper when someone buys the car and the car can be clean but if u call bmw of usa they will see that your car is salvage and they wont replace anything under their good will policy u will have the clean title in your hand but your car was salvage at some point so i wouldnt suggest u buying this car. Sorry if i m bad at english
