I'm 38 and like customs, but you can go "too far" with the customizing. I like the original door handles and original grill. Chopped tops are cool as long as they are in proportion to the truck. A windshield that's 3 inches tall looks stupid. Shaved drip rails and tilt front ends are cool too.
Most of all, I admire the effort put into the construction of ANY vehicle, stock or hotrod!!!
