When did you "know" you were a car guy?

When I was about 14 my Dad took me car shopping for my sister. They picked up a 74 318 Duster for her, and that sparked my interest. She and my Brother-in-law painted it metallic green and put Keystones on it. That got me even more fired up. Then my sister came home with another Duster 360 4-speed car that she wanted to sell. I took a drive in that one and I was hooked. Still have that car! Bought it 36 years ago
