I'm 54 years old, have about 50+ Hotwheels in my office, and every day I get on the floor with a one year old girl and play with my cars. She loves it, and I get a pretty good giggle out of it. Her favorite is my Don Prudhomme funny car, mine is my Thunderbolt. Right now I'm trying to find an early Drag pac Track. Right now she has the giant Lego's, hopefully soon we'll graduate to a proper set...
