$7000 is quite high for a sedan. (It is a sedan, not coupe, right?) Here is my short-list of things to look for:
1. front and rear windshield gaskets - when were they replaced? If the haven't been replaced, they probably leak. Front windshield gasket leaks into front footwells. Rear windshield gasket leaks into the trunk. Look carefully at the corners of front and rear windshields -- any white buildup on the glass or rubber (moisture indicator). Look under the front carpets (you must take the carpets out of the car and really give it a good looking over. Look under the rubber mat in the trunk. The rubber trunk mat is a real killer on lots of MB cars. It traps moisture under the rubber and you get rust. Look for irregularity under the paint on the outside of the windshields, particularly at the corners and bottom edge. If the metal is rusted where the windshields mount (the unexposed areas) your repair job becomes bigger than just replacing the gasket, which in itself is not trivial. Also look for rust in the truck rim
2. Heating and Air Conditioning. Does the car have AC? Did it ever? If not, make sure that the heater fan works on all three speeds. The heater fan is difficult and expensive to replace. If it DOES have AC, the fan for the AC is a different fan than the fan for the heater. You need to make sure both fans work, particularly the heater fan. The same knob turns on the fan(s). The TERMPERATURE knob controls _which_ fan gets turned on. If you have the termperature knob all the way off (ALL THE WAY) then the fan control will operate the heater fan. If you have the termperature knob even a little bit on then the fan control will operate the AC fan, and a vacuum actuator will move a flap changing the air flow.
3. Under the hood... I'm guessing that these are M129 engines - 2.5 L I-6 with 2 zenith carbs. I could be way off. Carbs can be fussy but if tuned well they are good. When you drive around it would be useful to see what comes out of the tail pipe when you floor the car. It would be useful to have a friend follow you on the highway and report back to you. Some smoke is OK, might just be running a little rich.
4. Make sure all the windows work (manual or electric).
5. Make sure the wipers work. Mine don't work right. I have to hold the foot pedal (frog) for the washer pump to make my wipers come on. Not a big deal though.
6. If you are taking it to a mechanic, knowing the compression would be useful.
I'm sure there is more but this is what I can remember...
