Having had 4 M.B. cars in the last 27 years, I can vouch for their unreliability and the unavailable, so called, Dealer Service.
Such technology will appeal to Corporate Buyers who can afford it ,but by the time the vehicle filters down to the Private Individual, all Warranty will have disappeared and even 10% of one Bitcoin will not cover the costs of repair. Leave well alone. Wait until Hyundai offers it with a 10 YEAR WARRANTY.
