I already proved you wrong on that point.I don’t see problems with some of that. Leasing agreements? Not sure what Tesla does now, but at first they had NO leases, then they did a deal with a couple of banks. Apple certainly already has financial industry experience with wallet, Apple Pay, their own credit card, etc. Leasing and financing will be pretty easy for them.
Direct sales? Again, same as Tesla. Buy the apple car from your computer, iphone, ipad, etc., on the web, using the Apple Store app, or some new app for that purpose. Visit a show room to see the car and take a pre-scheduled test drive. Salesman can help you buy the car yourself using a handy iMac sitting in the showroom.
Building: many choices. Even old car companies use contract manufacturers: https://en.wikipedia.org/wiki/Category:Contract_vehicle_manufacturers
Service is the big question mark.
Mark my words I am right and you are wrong, sorry!
