I love the fact that if you put all those vehicles end to end you'd reach around the world once! I love those big cars and trucks. Great job of keeping them up and running, not to mention looking good.
P.S. The only one your missing is a 1984 Chrysler Cordoba!
a great product is Amsoil HD protectant. It really holds up well and protects those "rustable" components. Other than that, CG Bare Bones is great on the plastic parts.
