I didn't find anyone quoting my my last job who even considering leaving the glass in for the respray - its the bare minimum for a professional bodyshop. Costs start going up when they're removing doors, bumpers, wings so they can spray door jambs etc. Quotes varied for my recent respray from €1500 or so to €8500.

I don't like recommending bodyshops anymore. Have never used them, but Dennings are supposedly excellent (and charge accordingly).
