It’ll never happen of course, but if dealers are going to continue to be thin on the ground, even in the US, how about each dealer has at least one traveling technician on call you can schedule time with and they’ll visit you at home? Especially for smaller repairs or software updates. Not talking heavy mechanical repairs but jobs where they can fix it in the driveway for instance.
I used a mobile tyre service for the first time a few months ago and the gentleman who showed up to install my new tires was professional, courteous, efficient and above all else very detail orientated. Compared to the hassle of taking time to go to a traditional tire shop, the noise, and general inconvenience it was like receiving first class service. Plus you get to talk to the person directly who is doing the work and build a rapport.
I’d gladly pay a nominal service call charge for IA to do this even for work being performed which may be covered by warranty. Big jobs or issues requiring time to resolve going to the dealer workshop still makes sense but for smaller things why not? How cool would it be to have a Quartermaster with a large tool box replacing the truck bed and Ineos logos emblazoned all over it showing up at your house? I guess I’ll continue to dream the dream.
