I want a car.. but I don't necessarily need to own it. In fact, I find owning things to be a burden. It keeps me unnecessarily tied to a location, working for things I don't need really need, and things I don't really miss when they're gone. Having had the opportunity to do some traveling and live abroad (South America, I'm from the US), it's really changed my opinion on owning lots of things, cars included.
For the past 3 months I've been renting a car because I've needed it for a few particular reasons. However, I'm very glad that I can simply return it at whatever time I choose and be done with the responsibility of it.
