A 300G convert for sale came up on Hemmings Daily. While this isn't, an earth-shaking event, I noticed something on the car I don't think I've ever seen. In front of the rear wheels is a chrome guard that extends up a bit from the rocker panel. Has anyone seen this option before? I think it may have been something custom made for this car and not a factory offering, but I thought I'd ask the group for input.
