We did the same for my daughter, Klyd. We told her that we were giving her my older daughter's car when she got her permit because my older daughter was getting a new car. Then, we told her that we had to trade it in to get my older daughter her new one. Little did she know that we actually got two new Sentras and hid hers around the corner.

At her party, just before the cake, my husband slipped out and parked it in the driveway with a giant bow and balloons tied to it. After she blew out her candles, we gave her a box from a local jeweler to open and the keys were inside. She just kept saying, NO, YOU DIDN'T, and then when she pressed the button on the fob, the car beeped and the lights blinked and she and all her friends yelled! It was a wonderful surprise.

Congratulations to your daughter. I'm sure she's thrilled, although I bet this is somewhat bittersweet for you and your wife - baby's growing up!
