KenP,

Thank you very much for the detailed post. It gives much useful information that I wouldn't have guessed by just looking from the outside of the 2 versions.

The W140 coupe is certainly much more rare than the sedan version, and given a choice I would pick the coupe too (... have a E320 coupe now ).

I saw a late model W140 coupe on the road a few months ago -- it was badged CL500, in silver, and looked absolutely showroom. Was thinking, how can one find cars like that these days -- don't people want to keep them forever ?
