Togo Brown on a cinnamon interior. According to my COA, this was a paint to sample color for 1977. The paint code is 413, but I believe Togo Brown was code 6411 in the early 60s.
One interior option that I haven’t seen too often is a black piece of trim on the top edge on the rear seats. Not a paint option, but a cosmetic option I have always liked on this car.
