First there is some clarification needed. The W110 body was made form 1961 to 1968. From 1961 to 1965 there was the 190c (4-cylinder gasoline) and 190Dc (4-cylinder OM621 diesel). In 1965/1966 the body was updated, at which time there were three models, the 200 (4-cylinder gasoline), the 200D (4-cylinder OM621 diesel), and the 230 (6-cylinder M180 gasoline). The 220 in those years was a 6-cylinder gasoline model, and had the W111 body, and I think became the 230S in 1965/1966. The W110 had the single large headlight and the W111 had the dual stacked headlights.
The automatics in those days were actually 4-speeds. In addition to the 4-speed manual transmission, there was also a transmission called Hydrak automatic clutch which was basically a manual transmission with an automatic clutch. I have not been around the automatics much, but would think that a manual transmission would be more valuable in one of these old cars as you never know when the transmission will go out, and will likely cost a whole lot to fix. Plus they were not very efficient. Manuals are pretty simple and usually trouble-free.
Don't know about the cracked heads. Which engine has this problem? Parts for the body are not the easiest to find, but I suspect the engines are not as hard, especially the M180 6-cylinder. There are may junkyards across the country, many in the south and east, that are dedicated to Mercedes. Also, may new parts are still available from the dealer.
As for power, a diesel with an automatic would be the worst combination. The diesel was not a powerhouse to start with (55 HP), so any power robbing device (including A/C) will make it worse. The diesel with the manual would be the next step up. I would think any gas model would have sufficient power, with the 4-cylinder with a manual being the most economical.
They are actually decent daily drivers and drive very well given their age no matter what the weather, but proper maintenance is a must, especially on the front end components. For the best daily driver, you will want to look for a 1963 or newer model as they had front power disc brakes as standard. Floor shift was also an option for sure after 1965.
