I have seen a 220SE Automatic Coupe and would like to know the differences to a 220SEb? What does the b stand for?

The lower case letters indicate a latter version of a model. In this case, a 220SE is a 128(ponton round body), production ended early 1960.
The 220 SEb is a W111 model, entirely different body, and commenced production mid 1960. They just used the same, but modified, engine.
I have a late model 220 SE coupe. Ed

By the way, the automatic, unless there was some radical modification, is a "Hydrak" clutch. The clutch is activated by sensors in the shift lever. Touching the shift lever activates the clutch, there is no clutch pedal. It was not a successful option, and most were converted to standard. If they are in good condition, and properly adjusted, they do work well, but takes a whole lot of getting used to. As I have said before, it is an aquired taste. Ed

To clarify Ed's point. The hydrak was on the 220SE to make it an automatic. The 220SEb had a real automatic tranny, but the hydrak was an option to go with the 4-speed standard and yes, it is an acquired taste.

There is a radical difference between the W111 sedan and coupe.
