No door lock switch. They all go down with the driver lock (when working properly).

Sounds like this is about a parts value car (that you could possibly use as a driver). Assuming mileage is in the 200k range I would guess value at $500-$1000 as a driver.

Only you can determine if it is worth it for you. Sounds like a lot of deferred maintenance which if you plan on driving it for a lot of miles will cost some money. You know the story..."There is nothing more expensive than a cheap Mercedes."
