I have asked that they either pick the car up and leave a courtesy car, or authorise a local x-part dealer to do the work.
At the end of the day I would be happy with a free fuel fill up.
Last time I went to Summit Garages and had to stopover, so fuel and accommodation was around £250 before any work was carried out. That was to sort a few recalls that hadn't been done.
I don't think I should be out of pocket every time the manufacturing standards of MG are questioned.
