Just been to the body shop with the RR and they say that the lower tailgate is not really repairable as the aluminium has split on the fold. New from Land Rover the gate is about £270 but the ones on ebay seem to have similar problems.
I don't mind posting the thing if you really need it, i could take some picks of it if you like? don't worry i wont charge you much for the thing!! anyway email me if you still want it and i can send you a load of picks tony___@hotmail.com
