These are two superb cars. The W111 coupe is so elegant. I owned several, and sometimes regreted not to have it in the form of a convertible. The problem with the W111 convertible is that I like it with the top up, and I find it ugly with the top down: it looks like some kind of a big barge and loses all the elegance of the Coupe (at least in my view). On the other hand, the Pagoda is a very nice little roadster. I like it with the top down, or with the hard top, but not with the soft top up. The solution then is to own both. And the good news it that in an equivalent condition, one can buy a Pagoda AND a Coupe for the price of a W111 convertible. So, like you, this is what I did, and I'm a happy man, like you surely are also.
Congratulations!
