I'm hoping to get this wheel arch tidied up on my fiesta mk5, is it bad enough to warrant replacing the whole arch? Admittedly is does look slightly worse in reality than in the pics, How much roughly will something like this cost? The car isn't really worth much so i don't really want to spend a vast amount. Ive been doing bits an pieces to it myself to tidy it up since I've bought it but wouldn't attempt any type of body work.
I'm struggling to find somebody to do it, the only place that was recommended to me aren't interested but that's another story.
