IS it a Grey Market car? Should be a 240D, not 200D unless it was imported. Probably not 200, as it would have to be federalized. Maybe came home with a soldier.
First good question for you -- would you purchase a car with the same issues from a class of car you are familiar with? Classic car that sat for 35 years.
Next, fill out your profile so that others who may be near you can point you to a reliable shop that deal with old Mercedes. You should also join MBCA so that you have access to tech events and meet other benz owners who can assist you.
Why was it sitting since 1983? All the rubber will be junk. Best to get it up in the air and be ready to do a full rebuild of at least the fuel lines if not the suspension. 35 year old rubber is not safe to drive around with. Most of it would have been replaced at least once by now had it been on the road.
If the car is automatic, these things are prone to not being able to get out of their own way. A stick shift will allow you to get more power where it needs to be when you want it to be there. The standard joke about the W123 240D is that you get more bugs on the rear window than on the windshield at highway speeds. IT is a heavy car with an under powered engine that does get very decent mileage. You could expect around 29MPG highway, but it would take minutes to get to speed.
I have not owned a W123, too ugly for my taste. There are a great number I have dealt with at PnP. There is some rust areas, mostly floors and such. A car that has gone nowhere for ages should have no rust at all. Given the miles, and stored inside, you should expect to find this thing looking as fresh as the day it was delivered. No paint issues, no rust, all records, tool kit, first aid, everything almost like new.
IF the car is almost showroom, you can expect that his asking price is reasonable. A diesel benz would be expected to fire up fairly quickly with a fresh battery and fuel. These things are built like tanks and come back to life more reliably than Zombies. I am at a loss though as to why it was not driven for so long. Must be a massive problem to sideline a car like this.
If you do purchase, the standard full fluid and filter change out will need to be done. The fuel tank may also need to be removed and cleaned, as the fuel tends to be a great breeding ground for algae. That will have plugged lines, filters, and more. Best to just drain and start with new fuel after tossing in a biocide. Drain the injection pump and install fresh oil, crack the hard lines and make sure you get fuel to the injectors (the hand pump should create enough pressure that the lines will drip at the injector head if you loosen them).
Citric acid flush of the cooling system would be good. Replace with Mercedes Coolant, not the green garbage. The coolant is formulated to work with the variety of metals in the engine and prolongs both engine and radiator life. Zerex G-05 is a comparable replacement to the Benz coolant.
If you are doing winter driving, you should install a block heater so you can light it off in the cold. Takes about 90 minutes to get hot enough that the fluids flow well. You will want to dilute the fuel during winter with kerosene so it does not gel in the lines or filters. Fuel does recirculate and eventually gets warm enough to flow fine, just the first 15-20 minutes on a cold morning you might plug filters with cold fuel. Winter driving in salted areas does require that you do a thorough job of undercoating the beejeezus out of the car. Salt and gunk will start rust in places you did not know were on the car. Some people do a spray of engine oil to the underside in fall to defend against rust. A few have been known to install underside wash systems to flush salts away when they get home.
Given all the caveats, these are great cars that do last for almost ever if taken care of and shown respect. They were superior daily drivers when new, and have a very loyal following to this day. This model is well known to rack up hundreds of thousands of miles and to be extremely reliable year round.
I am just very confused as to why it was only driven for two years and then stowed away.
