I have gone for an Austops again. As most people will say again and again, its the fitter and not the roof thats the most important part. Reimo, SCA and Austops are, as i'm aware, the only ones TUV approved. If its good enough for VW, then it will be good for me. I drove from Glasgow to Halifax to have my roof fitted as I was recommended the fitter, he comes highly rated.
Will be picking the van up next week and will post some pics of the roof.
