So, in summary, you do not need to be running two cars unless you want to. It’s a shame that so many people misunderstand this as there must be an awful lot of people incurring substantial and completely unnecessary additional costs. A Motability car on its own is costly enough!
TBH, its the abuse some give when they know you are driving the car too, as they clearly dont know whats allowed, I spent ages making sure that I would be able to drive myself, as the wife is mostly house bound / bed bound.
I would add, on this, some dealers will visit, some will allow you to collect on behalf of partner if they are unable to due to health reasons at pickup time. Its not strictly within the rules I dont think, so its definitely an ask and see kind of situation.
Its a shame really, as covid showed what was possible but seems motability removed the option for a video call etc which would have made many peoples new car experience a lot less stressful.
