RE: 1985 300d vs 1985 300sd
Having never owned either but shopped extensively and tried some of both before making my final decision, I would go with the SD. The mileage is not a problem, as long as its in good shape meaning no rust, engine runs well, not too much smoke, that sort of thing... it'll run longer than you want it to if it's in good shape.
I personally feel that the SD has a more attractive body and tend to suspect, as it was from the higher class of car, that it is probably made a tad better, though nobody could say that mercedes made anything too badly.
That said, there's not much technical difference, it's down to personal taste. if you like the looks of the D better, if it has less rust, if you like the mileage better, whatever... there's nothing WRONG with a D.
Bottom line: Personally I'd go with the SD but I can't come up with a really good reason for it so go on and get whichever one feels right to you... a Benz finds its owner, not the other way around.
Hope this was helpful.
