This has been my concern here in my own country Nigeria. No auto dealers or automakers has ever accepted any crypto particularly BTC for purchase payments
Well in some developed countries, where technology is really advancing and always embressed, wholeheartedly, You can purchase a car and pay with Bitcoin. Some Car producing companies in US, Dallas, Kasas etc. announced their acceptance of Bitcoin for car purchase.
Almost anything can be purchased with Bitcoin nowadays, and Car purchase is not exempted.
