I haven't ever really been that into cars, but I remember loving the Lamborghini Gallardo as a kid... just because Akon mentioned the car in "Smack That".

However I did have a phase where I would always sit behind my dad's Ford Sierra's wheel and act as if I were driving. One time we were at the garage and dad was doing something outside while I was playing behind the wheel again, not looking out of the window. I then glanced out for a moment and saw the car was moving. I panicked and started screaming. Dad ran to the car fast and pulled the hand break on. I got so traumatized I still don't want to sit behind a real car wheel.
Dad has tried to teach me drive two times (on a Honda Civic), but they were a total waste of time. One time I just refused to sit behind the wheel for a long enough time to get him slightly pissed off and give up. The other time he made me back out from a parking spot. I panicked once the car started moving and noped my way outta there.
