As mentioned, I only just purchased the car. The damage was already on it. At a glance I'd say it's been scraped pretty hard against an immovable object (eg concrete pole) as there's a little scratching to go with it. Previous owner has taken to it with a hammer and knocked it out to make it look (arguably) better. If they hadn't done this it would be an even easier repair!
Noone interested?
$300...
If noone takes it I'll just sit on it for a while until my other one's running and do it up then. Just a matter of storage...
