What's weird is that my Dad was a Ford guy who owned a lot of GM products. My first car (at age 12) was a '52 Plymouth Cranbrook sedan I paid ten bucks for - and drove it home! My bro-in-law is a huge Mopar guy who worked in many capacities for Chrysler from 1965 - 2011, so he is who I got the Mopar bug from...even though he, too, owned many hot Chevys back in the day - a gasser '56 Chevy 210, a stock 63 Corvette split-window and a '65 Stingray ragtop.
