It really depends. Sometimes I carpool with friends (if we're going to the same destination), sometimes I ride with family (if we're going to the same destination)but usually I drive. My friend claims my car is "Of Mafia" because its a 2000 Black BMW 323 CI with tinted windows. Yes its used. Yes it has 130k miles but I love it. Yes its paid for. And did I mention I totally did not have to pay for it because a guy crashed into my other car? Yeah, so hey no complaints here.
