I get 90%+ of my trips around by walking and biking, occasionally by public transport and only a few times per year I need a car. Living in the Netherlands.
No, I don't and I haven't felt the need to buy one either. For the few times that I do need a car I'm lucky enough to have family living close by that is always happy to let me use their cars. But even if I didn't have family living close-by renting a car a few times a year is probably way cheaper in my case than buying and maintaining my own car. Owning a car does have some advantages, but in my case I think the disadvantages outweigh the advantages. Disadvantages are things like: Extra costs for buying the car, maintenance, parking and insurance. Taking up extra space in a crowded city and bad for my health if I get too much used too it.
I would buy one if I really needed one for a job, but so far I really don't need it (and I could always still buy a car if I do need it more often).
