They didn't even get that far! They had it for 2 hours and then tried to tell me it'd be another £250 because the track rod end nuts were ceased. My response, after observing said bolts with the mechanic was..... do you not have WD40?
They then agreed that I could take it back and 'uncease' the bolts myself and there would be no extra charge. I could see the mechanic was mortally embarrassed, but had to tow the party line :/
