1985 Mercedes-Benz 300CD

One of the more interesting things about the legendary Mercedes-Benz W123 chassis is the difference between the production numbers for the sedan, estate and coupe bodies. As you might have guessed, the sedan was the most plentiful at just over 75,000 units made from 1981-1985 as the 300D with the OM617 turbo diesel engine. Next up was the 300TD station wagon with a little over 28,000 units. Bringing up the rear is the 300CD with just 7,502 cars. The easy math here says that from every 10 300Ds, there is only one 300CD. That explains why you can go on your local Craigslist and find a handful of 300Ds, but the coupes? No where to be found. As a result, the demand and values for coupes have always been much higher than the sedan not only because of the rarity, but because they are cool cars and a pillar-less coupe is always classic. Today, I managed to find a really nice 1985 300CD up for sale in Florida and luckily, this one is a wonderful example.

This is as fine as an example of a W123 coupe I’ve come across in a long time. It has been enjoyed at 133,000 miles, but my goodness is it clean. Exterior, interior and engine, all nearly spotless. Nautical Blue looks great on this car along with the Palomino interior, but the real gem is the condition of the wood. When it has that deep, rich shine, it just really sets off the interior. Under the hood, this being a 1985 it has the slightly different turbo setup and a 2.88 rear differential that lets you sneak a couple more miles per gallon of off this sleek coupe. All in all, there is nothing about this one that tells it is nothing but a gem.

The seller originally had a Buy It Now option of $8,500 on the 300CD and I thought that was more than fair. These coupes are twice, sometimes three times, the price of a comparable 300D, so $8,500 would have been a good buy. Someone did put an opening bid of $6,600 on it so it wiped out that Buy It Now option, so now it is open season as to where this one ends. My guess? I wouldn’t be shocked to see to hit $10,000. I think we are at a point where you won’t lose money on this one as long as you keep it the way that is it. There is nothing about this car that says it can’t stay that way.

    Lovely car although some listed and potential issues that might end up being quite pricey, such as the vacuum door locks not working and nothing about the somewhat troublesome and expensive to fix A/C. And of course the mileage will be hard to verify with a switched-out odometer.

    Mind you for $8500 I completely agree that it would still be a good deal.

    What makes them even more rare, the combination of Diesel with Coupe has never been offered in Germany at the time (same for Diesel in an S Class….)
