1982 Mercedes 240D 86,595mi One Owner, garage find, no rust unmolested survivor

Local, one owner, original owner bought 8/23/1982 at Trail Mercedes in Mobile Alabama.
No rust, an unmolested survivor. Cosmetically it is dirty and unpolished, shown as is for its true provenance. No armor all slick detailing. Nothing to hide, no apologies.
It is valuable to someone who wants a low mileage original.
Only thing I've done is adjusted the valves after getting her running, and added Diesel Purge to clean the fuel system. I have added fresh diesel, no cetane booster, I want her to run normally without additives which are misleading.
Automatic 4spd transmission shifts smoothly, not hard shifts, and she shuts down with the key, thus the vacuum pump works properly. I am not confident of the preglow relay, she starts immediately when warm, not so when a cold start. Idle is smooth thus I believe injectors are satisfactory. I believe the front suspension needs new bushings, of course. I believe the right rear brake caliper needs repair or replacement.
I am being very candid and forthcoming of my observations of the mechanical diagnosis.
She sat in the garage for years. I have driven her on the road for approx 200 miles, I have not changed pre-fuel filter nor fuel filter nor oil. I want you to see her as original, therefore I advise you trailer her home until you do all services. I trust her but because you are a stranger and its ebay, I have to state the sale is 'as is - where is'. We live in a lawyer world, so there is the legal schmegal.
Original hubcabs come with the car. The bundt wheels were an owner upgrade years ago, not on the original build sheet. Yes the front left fender is a replacement, the lady had a fender bender, my observation is - not professionally repaired; I see used parts.
More pictures available. If you do not know Mercedes and 240D Diesels, do not ask me questions because you are learning. This car is for a specific audience, not veggie-heads.
