I have a friend that he lives in a auto-caravan. But he didn't bought it. Is in leasing. Practically a rent without any responsibilities, taxes etc. And when is about to expire the leasing, he just change the car for a new one. But yeah this ia another scenario where you pay a rent that could be higher than all those old cheap cars.

I would choose the cheap cars method. I did that years ago when I was "in love" with BMW cars and liked to have fast and powerful cars. But that era passed away when I realized how much money I spend in cars instead of Bitcoin. So I sold my lovely nice BMW and bought a bike and really cheap car that I can dump it anytime when is dead. The rest of the money I put them in BTC. I don't use too much the car because I live in a rural area, but I use the bike and walking.
