I grew up with a lot of older brothers that worked on cars and had cool cars: Impalas, Camaros, even a Corvette. I've just always loved cars.
I have a collection of 1:18 diecast muscle cars. I was up over 300 cars, and am now down to about 125 cars, with several still currently for sale.
As you may be able to see from my collection, I especially like muscle & sports cars.
I also love racing. Mostly road racing type events. I've been to a few Nascar races, but it just doesn't quite do it for me.
