I know someone who owned FOUR and I find that ridiculous. For a single person who is not swimming in cash, it seems excessive. I can understand owning two especially if you live in an area where the climate changes a lot. You can have a summer car and a winter car. I personally own one car and I have a bike.
I just have the one. I am going to be selling it and getting two new cars, one for myself and one for my wife. I think she will end up wanting an EV mini and I will likely go with some sort of compact EV SUV.
