Very strange book not to list a 220S for 1963. It would definitely be a W111. W110's are four bangers and diesels. I think they are also the second generation 65-67 230's (Not 230S's) that were straight six engines shoe horned into the short nose four cylinder body style.

89K miles in nothing for a 41 year old car, can that be right?
