I love 1958 GM cars, especially the Chevrolet, as well as the Buick - with the huge grille with hundreds of individual chrome squares. But for some reason, I never cared for fender skirts and Continental kits. Perhaps I am just odd, but I love the look of 50s cars that do not have those parts.
The coolest thing about the 1958 Chevy was how restrained it was compared to other makes or even later models. Put a 1958 Impala next to a 1959 Impala, and you will see just how conservative the '58 looks.
