My rear arches and starting to bubble and abit of rust so i want to get some new arches.

Got a quote from my local bodyshop(this is to supply parts/materials and fit)
Labour £255.00, paint and processing materials £72.00

So all in all its going to cost me about £327, does that sound reasonable because ive absolutly no idea as ive never took any of my cars to a bodyshop etc

Cheers
