Off to France next month via the tunnel but back Caen to Portsmouth on the Ferry three weeks later. Am a bit concerned about the Ferry as the Plus 4 has less ground clearance than either the 4/4 or Roadster but cutting the two gearbox mounting bolts back to the locknuts has helped a lot, must have gained about 1cm. The big ferries are OK as the ramps are fairly gentle but some of the smaller ones can be a bit challenging. I would check to see if the bolts on your car are like mine were as its a quick and cheap improvement.
