when my old 306 was 'cuddled' into a crash barier by an HGV i had the work done at Minimec in bracknell through my insurance.
When i came to sell the car I admitted to the bloke buying it that it had been repaired, cos that may have shown up on the HPI. He got an AA bloke to do a full inspection on the car, and the AA bloke was well impressed with the repair, said he may not have noticed it if he hadn't known to look out for it..."
