Depends how well he checks wheel alignment. How much is 15' of box section?
To be honest I don't see how anyone can pay for adjusters twiddling, you learn nowt, understand nowt and you're buggered the next time you change anything or anything changes you.
Oh and on an SV it's even more retarded because the stock is that far out that you can't make any useful adjustment!
However if anyone wants their sag set and insists on paying me £40 for the privilege then I wouldn't say no
