Exactly $34,612. In today's dollars that is about $60,000. My SD, in 1980 retailed for $33,473, which is about $72,000 today. So I am suspecting your sedan will be in the same price range as my wagon. With regard to these original prices, keep in mind that MB built in a nice fat profit for the dealerships. For my SD, the dealer's cost was $26K and change, so they made a $7,000 profit on that car.
