quite a difference...for comparison I will call another main stealer (different franchise) in Glasgow and see if there is a price difference.
OK here is my findings thus far..
1. VW Arnold Clark Jordanhill (Beissbarth) want £146 to fix, 2 hours labour

2. VW verve Dalmarnock Road (Hunter) want 2-3 hours labour....I didnt hang about to get the price.

3. No point in going to Advantage in Stirling as they will undoubtedly charge about £70 per hour and give the same spiel.
3. Drivers Glasgow (where they do the Revo etc), will look at it and if it only needs front tracking charge me £30. Thereafter it depends how much it is out. I didnt determine the actual machine that they use, they are a generalist however so don't expect it to be a beissbarth.

4. A4Audi and another independent "specialist" state that they cant do it.

5. Kenny Brown Motor Engineering in Hillington seem to get a good reputation for knowing their stuff I am just waiting to talk to Kenny about the costs. But yes they can do 4-wheel alignment at least.

All this lol...and you know, I might not actually need it

Oh well keeps me from surfing porn I guess
