I use these silly little toys as a way to turn off my brain from the regular world. I don't watch TV hardly ever, but I take as many opportunities to sit in the shop to just rearrange the work bench. I call it therapy. It lets me not focus on my problems with clients at work, or national politics that I have no control over, and sometimes lets me escape my wife when she's in one of her "moods."
If I didn't have toy cars to take apart, clean, polish and reassemble many times, I'd have too many nervous ticks to analyze.
So my cars tend to look a little anal retentive.
