Help Me Understand Why

Truthfully, 40-50yr old cars aren't exactly falling out of trees around here (regardless of what they are). I don't remember packs of model A's marauding the streets in the 70's or 80's either. ****, the other day I saw a Pontiac Ventura. The fact that I actually noticed is amazing. I've probably seen 10,000 in my life and never gave a second look till yesterday.
