Well I took the wheel in question off last week and it looks like the wheel is buckled. I hit a pothole before I left for the trip (Aberdeens roads are a disgrace!!) when I looked at the wheel initially it seemed ok, I thought the tyre would have taken most of the blow and it seemed fine!
Anyway the car groaned its way round 2700 miles of european countryside and I even managed 2 laps of the 'ring!! Probably a bit risky but I couldn't resist!! The car performed brilliantly on the twisties, keeping up with much more expensive machines, and flew by an Alfa 75 V6, but unfortunately couldn't get over 80 on the straights.
I am now back home and planning on doing a lot of work to get the car ready for a return trip next year.
Stixy, just read your post about the bearings. Good job you got them out, I'll be having a look at mine in due course!
