YMB has always been kind of meh to me. I liked it somehow when the car came out but there are so many better colors imho like Mineral White, Sakhir Orange and SilverstoneII in the standard ones. Black never again for me, I used to have many black cars. Mineral Grey I think is the dullest color of them all, especially on the M4 the car looks almost like a standard 4-series Coupe.
I have now a Speed Yellow car, I wasn't too fond on it but as it was a good price and was almost fully loaded, I went for it. Now I love the color. So you never know surely, I might like YMB on the new G80/82
