Yes, you are in for trouble, but it's going to be entertaining at the same time.
My two Daddy's Little Girls are now 22 and 19, and it feels like Badawg said above that it was yesterday that they were your girls' ages.
My younger one is more is more interested in my Mopar, though; she drove it to high school several times her Senior Year. Every time she did, she'd come out at the end of the day to the parking lot to find several boys who she'd never met before hanging around the Dodge waiting to find out who owned it. They had her open the hood, start it up, etc. She said she knew when she drove it she'd be in the parking lot for at least fifteen to twenty minutes extra, just to show the boys the car.
