Hi Len/Paul,
I park in my garage from 5pm until 7am every day, the remaining time it is in a works car park with no trees, so I know it definitely wasn't picked up in my ownership.
As I said it was there very slightly when I picked it up in Feb this year, but has got worse over the summer, maybe the sun has affected it?
My local dealership have offered to try & polish it out for £85 which I have forwarded to the selling dealership last Tuesday, but no response yet.
I have tried Meguiars scratch remover, but it hasn't touched it. I am concerned too much work on that area will wear through the clear coat.
I will give the selling dealer until the middle of next week to reply, but I am sure they will say it has been caused by me as I didn't report it until 6 months after purchase, I do have pics from June when I noticed it getting worse.
