I recently contacted Horton SEAT about this rear bumper insert for a face lift
MK3 Leon FR. I want to paint mine to match the car, but also keep the original one in the event I decide to swap it back. The face lift version is very slightly different in shape but I was quoted £49 including VAT with the Cupra.Net discount of 10%. Postage was extra. Either Horton SEAT or Listers SEAT will be able to quote you. Hopefully this will give you a starting point.
