I am going to get the dealership to put a big red bow in the back of the SAV and will put it on there Christmas day.

As far as giving it to her, I am going to park it in my mom and dad's garage
(we spend Christmas there) and will have her go to the garage for supplies (read beer and wine) and she will find it in there. Their garage is seperate from the house and you can either access it from a side door or through one of the main bays. I am going to have my dad lock and "lose" the key to the door and then open the main door for her to find the new X5 in the garage.

I think it will work well...
