Controlled temperature seats in the car. My first car didn't have anything like that, so I never really thought about needing it. But then I got my second car which had heated seats, and when winter came, oh man, I finally understood the appeal. And then summer came and I had to borrow my parents' car for a week, and it also has cooling seats... They are fantastic.
On that same note, Bluetooth in the car. Going by aux isn't bad, but it is less cords I have to fumble around with when I first get in. That being said, I still carry a couple backup CDs just in case, lol.
When I was younger I fell off a homemade merry go round some neighbors had built. Got hit in the back of the head by one of the horses as I tried to get up. Ended up with staples and a lovely scar.
