All 3 cars I've owned have had some nifty feature. I'm talking about a feature that isn't necessarily advertised, or maybe just one that's not that special. It's just...nifty!

The Accord I had in college would roll all its windows down when you held the unlock button on the key. It was really, really nice in the summer. This one sort of toes the line of nifty, I honestly wish all cars had it.

My Kia had speaker lights that beat to the music. Nifty!

On my Sonic, the rear wiper automatically wipes if you are in reverse with the wipers on. It's a nice little touch. I honestly didn't know this was advertised until just now.

So what do your cars do that you think is neat, or nifty?
