Being in topic I think that buying a car a house or something else with bitcoin has been possible recently. Or through bitpay or through people to people accepting bitcoin.
Personally I don't think it as a good idea because the price of Bitcoin will be sky high in some years and I feel you can buy 2 cars with the same amount of Bitcoin then. Well, it's your personal choice and It mostly depends on the country you live in. If it's U.S. or Japan then you can buy but in other countries I don't think it's possible yet.
It depends on our needs, if we can't live without a car in the next years then it's ok to hold these money but the wait sometimes doesn't worth even if the price doubles.
A car isn't a luxury nowadays, it's a need but depend where we live and how far we have to go with vehicle, but buying a car when the bitcoin price all time high is the best part of this story.
