What are the basic differences between the 300D and SD...I'm thinking years 1983-1985. Are the SD's two door and slightly bigger. I'm interested in Safety so initially thought the SD would be bigger and Safer, but I really want a 4 door. Are they both just As strong and Solid and Safe mechanically. I've been told diesels last forever and I like the style of the early years....ANy advice on Year?....and again, do you think the 300d to be as safe as a 300SD...any years better than others?.......and what should be my upper limit of mileage on the car I should consider....
Thanks Much,
