Yeah.. it's quite hard to show in a picture. It's not that bad to be honest. It didn't detract me from buying the car in the first place.
It's about 8 inches across down the middle section of the roof. It was like that when I bought the car and I was told it might polish out. TBH, I'm not too good at polishing/cleaning cars! lol.
You could get away with paiting just the middle section between the two lines on the roof. If you like, I could get a quote for you for the paint work, so you have a rough idea? If I remember later on, I'll go for a drive to the bodyshop.
TBH, I would say £100 max to sort it. It's just not bothered me that much to go and have it done.
As soon as the weather clears up, I'll try to get as good a picture as possible.
