I agree with Tomguy that a later 111 coupe would be a wiser move. The 220s are so widely perceived to be underpowered that it's hard to imagine them ever having strong resale. The 2.8s and 3.5s are stronger and easier to maintain. Whatever you get you're going to put some money into it, which is tough to do if the resale value isn't there. This is just personal opinion but it seems to me that the coupes from later in the 70s and early in the 80s lack the panache to ever amount to much.
