This is the dream car for millions of people and god knows how many of them can own this in future. At least not in my country you can buy any car with the crypto currency as currently it is not considered as a legal tender to trade anything here with the coins.
You are really lucky that you have dealers who are accepting bitcoin as a mode of payment for purchasing a car but the scenario is not same in all the countries especially in underdeveloped and developing countries as most of them are still not aware about bitcoins and in that case you cannot expect that you can buy anything using bitcoins and car is an exceptional case and for that to happen people need to wait for a really very long time.
