Quoted £3400 - £3600 including removing the sunroof. Which involves removing the sunroof tray by drilling out spot welds and cutting the welded mounting points with a cutting disk, breaking the bond to the roof skin with heat and wire, cleaning it up, tacking some angle steel to the outside of the sunroof on each side, tacking some 4mm TIG wire around the edge of the sunroof where the seal would go, setting it in the hole, welding it up with lots of spot welds to avoid heat distortion, removing the angled steel, grinding the weld flat, treating, skimming, sanding, then prep for paint.
I've also bought a non sunroof headliner board. RIP sunroof.
Asked if they can do my exhaust and brake re-build while they're at it...
