@SteveRacer - She will get to drive them as they (both car and her) are available, if she wants to drive them. I'd let my 26yo son do the same, but he's in the Army, so his availability is pretty slim.
@SteveRacer - Having a daughter isn't that bad when they get older. My daughter is a little high strung sometimes, but she always comes back to hug on Daddy. I've always been her favorite parent, no bones about it. She still goes to talk the girly stuff with Mom, but she knows she has me wrapped around her little finger, so knows Dad is where it's at, lol.
