My dad and his dad were Chevy guys, so we grew up that way. A few years ago, my dad liked the diesel engine in the Dodge pickups better, so he and my brothers went that route.
My other grandfather drove Chryslers and Cadillacs. He was a farmer, but never drove a pickup. He would drive his cars out into the field.
Fords were considered evil in our family for many years, but I have a lot of respect for the way they've stepped up in recent years.
Personally, I think Cadillacs are great. I used to drive Pontiacs.
