Dealers can, as you can do, go to the DVLA website https://www.gov.uk/view-driving-licence and obtain your driving licence details.
That’s what car hirers do but I’ve always found that dealers / Motability are over strict for seeing the actual driving licence. I think that’s just down to them not having realised were in the 21st century now and everything is a data stream.
I hoping I don’t have trouble when I order in July because I reach 70 years old mid October and my handover, should it be on time, is the end of October and driving licenses have to be renewed every 3 years once you hit 70 so a great time for ordering a car when they don’t except the electronic procedure that everybody else does, or, do they except it?
