Sunroof Repairs: Who will touch it?

I've been phoning around and trying to get my sunroof repaired (on a 2010 Yeti) and no one seems to want to do it - not even the main dealer!

Earlier this year it refused to close fully, made horrible noises and had to go to our local garage to get it shut anywhere near closed. From what I know happened and what our local garage said, it is something to do with the arm on the left (passenger) side that has broken.

With the storms we've been having up here (West Coast of Scotland) it has been leaking appallingly so the passenger footwell is flooded - presumably because the A-pillar drain tube is now blocked.

Just spoken to the main dealer (three hours drive away) and they have said that I'd be better of going to a body shop! If they were to have it in, it will be only to investigate before quoting (fair enough). But they may say that they can't do it, put it all back together leaving me with £110 per hour bill and nothing to show for it as it'll have to go somewhere else (who will potentially do the same).

What experiences of having sunroofs fixed have people had on here? Who has actually done the work?

Really am stuck as I need a car with a towbar (and no-one has a courtesy car with one of those) and would have to take a day out just to get the car to the garage.
