I was in the services on the m40, the first ones you come to after you join from the m42 southbound, and wasn't paying attention to the gigantic speed bumps in the car park. It was one of those pavements type thing that are raised to fo the bump. So over I went slowly and grounded the middle of the car, nasty loud bang. Nothing looks like its hanging off but you can't really see much when it's on the floor
