I had one almost identical in the late sixties. It was only a 220 though not a 220s.Still the 220 had the six cylinder engine. Carb issues where not a great problem then but really are now.

You would have to run up the engine to see what you had. Has no great collector value here unless original mint example. Might be worth more in europe. Especially with the lack of rust I see.

These cars were built much better than later examples of mercedes. I found it a fun car to drive but you had to be careful about tires on the front. Wrong tires and it would seriously understeer.
