Thanks for the quick responses.

B&M Centre would have been ideal but we only have the one car and Yoker is a fair trek from Prestwick.

There is a BMW/MINI specialist in Ayr http://www.ayrshirebmwspecialists.co.uk/. but I’ve no idea if they are any good.

I’ll hold off speaking to the RAC until after the weekend as I’m still on sick leave until Monday.

Maybe someone will have a recommendation closer to home.
