I took mine into Colbournes Guildford today, as it had a couple of spots and loose paint on the o/s/r wheelarch (a common problem apparently). They checked it out, and refused my claim, as it had already been repaired in this area, and badly. Still waiting for their quote. They said it didn't matter that I was 3rd owner though, it's the car that is covered for 12 years.
Got a price of 240 from Bells Accident repair in Guildford, which included sorting out 3 other scratches on the same wing.
