On our '02 replacement X5 (3.0) that we have just put all this work into after it was leaking from about everywhere it could when we bought it.
My daughter did her first deep clean yesterday. As she was vacuuming the passenger seat, a razor blade came out into the vacuum from a crevice in the car.
Can you guess what she found under the seat?
It's a good thing she hasn't been pulled over, because the bag with white powder in it probably would have sent her to jail.
The respect-o-meter for the prior owner just keeps going up.
