You could always ask the dealership for a courtesy vehicle,it wont be adapted but if you could manage a standard vehicle give it a go…you might have to give the dealership a week or so to find a workshop slot coupled with courtesy vehicle availablity.
It doesn’t work that way anymore: the dealer now needs to raise a ticket directly with RAC. And RAC refused. The dealer is more than happy to give me one of their vehicles. But what will I do without left foot accelerator? I won’t take my chances with it on M3.
Never had a problem at my Ford dealership..always very helpfull in providing one of there own courtesy cars for any in house sevice work.
