Colors and tastes changes over the years, so green which seems to be a color that's "out" now might be in again sometime. In this car's heyday of the 60's and 70's, every British marque had a substantial portion of production devoted to BRG (British Racing Green).
Today, despite the lavish assortment of colors in the palette--actual production of MB cars for the USA at least, is pretty dismal. Let's see, 98% of production is Black, White or Silver. Go to the Port of Baltimore where they arrive, and over hundreds of acres that's all you'll see--with the little exception of a red or blue sprinkled in, probably because of customer order. That's just a little bit of a wider variety then old Henry Ford envisioned.
My subdivision, built in 1991-1995 has 330 homes in it; about 328 are some shade of beige or taupe "for resale", with matching beige carpets. (Mine is Nantucket Grey, and carpets range from blue, deep blue, to black) Color is indeed a funny thing.
Celebrate the difference if your 113 is something other then White, Black or Silver.
