I agree that the 747-8 does look rather good, in a sort of classic way. Coolness has never had anything to do with the age of a basic design, as any classic car owner will say. It just is.
If I could find roads wide enough, had a garage big enough, could be assured that something tangible would happen when I depressed the brake pedal, and I could afford the petrol to run a 7.7 litre V8 (8-10 mpg tops), I’d happily run a 1970 Cadillac as my everyday car for that reason.
