I was surprised at the pic Harms posted, then today, I checked the gap on my car, same thing, fingers easily inserted. Also worth mentioning is the radius of the door corner (behing scotts arthritic middle finger knuckle ;)) is much smaller than the radius of the rocker. It's almost as though the rocker forming dies were not designed with the door frame and skin available. Either that, or extra clearance for body twist in high hp cars?
