Have 2 nice big dents in what i thought was a sideskirt but is actually a rear quarter panel, or something ha.

it is basically the rear wheel arch and whole side of car behind the door, running back to the boot. A fairly big piece. Have been quoted £1500 by a ford garage, just for the part!!!

Was wondering if anyone knew any reputable places would be able to sort me out? Also if you know what price?
