I visited my parents this last weekend for Mother's Day, to pick up my new car, and to learn how to change out a differential on a 1990 525I BMW. My Dad loves to buy old BMWs, fix them up, and sell them.
I managed to screw things up a bit, but the differential DID get replaced, so...success.
I learned some things and got to spend time with the Poppa.
