Did somebody say YARIS? I also bought a Yaris about 6 months ago, and I really enjoy it as well. Lots of fun to drive...and I do a lot of driving for surf so had to do something about my gas bill (and my carbon footprint!). Like Craig says gas prices affected my car purchasing decision, but not my driving habits...I'm still driving as much as ever, just doing it with a lot better MPG.

One distinction I should probably make is that most of my driving is to work, as I moved close to surf. So, my driving habits have somewhat changed: now I walk to surf, and drive to work. Opposite of before. But better prioritized, if you ask me!
