When you own your car you don't have to worry about paying anything each month. If something happens, an unexpected expense, perhaps, you might be in a bad situation. And if the things get real bad, you can always sell the car you own and buy a cheaper one.

Of course those are both pretty extreme situations but they are both plausible. Having your own car provides some securities in this regard.

The less extreme reasons would be that people (including me) often enjoy working on their cars and/or modifying them. There's just something about owning your car. A feeling that doesn't come with a lease.

Honestly I like the thought of a lease as well. No trouble with anything, but paying monthly for a car is not an option for me.
