I'm not sure on an exact time, but sometime around being 10 years old I started to like cars more than just liking ALL of the matchbox cars I had. Some became cooler than others. Some were completely undesirable and were "sandbox" cars.
As I got a little bit older, I got books about cars. Then there were drawings and posters of cars. (and monsters). I liked the countach, the corvette, and of course, the Porsche 911. This is the pinnacle of what I thought I would ever own. I never imagined being able to have one.
