Cars
When I was younger, like in high school, I was really into cars. I hung out with a group of friends that just loved cars too. We would do all sorts of cool things to the bodies of the cars to make them look really awesome. We would even do things to the insides of the cars as well. One thing that I didn't have, but many of my friends had, as an addition to their fast vehicle were radar detectors. I never really had an interest in getting one, but they all just loved theirs. To each their own I guess.
