The car needs to be inspected by an independent BMW dealer/mechanic and provide you with a detailed report of its condition.
imo, I wouldn't buy a used car unless it was a CPO, had the maint. records or inspected.
Can you get the VIN? If you know where the car lived, maybe you can call some of the local dealers, give them the VIN and see if it's in their computer.
Are there any other cars available in the same price range in your area?
