Why enthusiasm for cars & why it matters

I'm 75, now, and have been Nuts about cars, since I was 14. I had a Model A Coupe, with a Flat Head V8 in it - transplanted from a 40 ford - motor - trans - wheels - brakes etc. - VW bucket seats. -- My initials are RPM. I tell people that My Mother must have known that I'd be a Motorhead.
