For me, the Prius C2 is not just my first hybrid car, but also my first car with any kind of high-tech or "bells and whistles". Heck, my last car (though it did have a stereo) didn't even have a CLOCK, and the only thing automatic about it was the transmission. I know I'm not the only one on in this forum having this experience, so this thread is for us newbies to go "gee, gosh, wow" about all the cool "toys" in our cool new cars. So... what is your favorite bell or whistle? What just tickles you when you use it?
