Also, with the Tesla model dealerships don't really work. Every car Tesla sells is made to order. There is no inventory sitting around at dealerships. The customer orders exactly what they want and it's made to order. This is very different than a traditional dealership where the dealer buys an inventory of cars then turns around to sell it to the customer.
Yeah it seems the only reason you'd want to go to the dealership would be to look at the car and maybe get a test drive. Tesla should crowdsource this to their user base. Maybe they could receive a spiff off of their yearly maintenance fee for demoing the car for prospects. What Tesla driver isn't going to want to show off their car? Everything else from optioning to ordering could be handled online.
