Luckily I remembered seeing a local Citroen garage 10 miles back so we drove there in my friends car (convoy of 3 to le mans), and pointing at a bx there and using a lot of sign language they came and picked me up. I even managed to laugh when the bloke in the garage got in my car to roll it off their truck but got in the wrong side as he forgot it was RHD heh.
Crambed into the other 2 cars, carried on to le mans and picked it up on the way back. Only cost £180 for the recovery and fitting of 2 new rear shocks as they did the other side as well which was not bad I thought
