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
maybe not all car dealers can accept bitcoin as payment, only those who already understand about bitcoin, and those who live in countries that already recognize the existence of bitcoin. because I have also heard an article about a car company that started receiving bitcoin as payment. maybe you can look it up on the internet. there is one of the luxury car companies that accept bitcoin.
