I have the option to buy a 1982 MB 300D with 144,000 miles from a Goodwill (Donated Car) for $3500. The exterior is in great shape all orig glass, great silver paint and only 3 tennis ball size rust spots in 3 different corners of the lower body. The interior looks like it's in perfect condition and even has the ancient carphone still attached. I don't know anything about MB's and was wondering if the price was a good one or not. They would probably let me start the car, but not drive it off the lot. If you do think the price is high, what would be better? Thanks!
