For some strange reason, one—but only one—of the supermarkets in my area often features interesting eighties cars in its parking lot. Back in mid-2016, there was a Mercedes-Benz 300CD Turbo coupe casually parked among the crossovers—a good enough reason for this blog entry.

“A singular new achievement”

1985 was the last model year for Mercedes-Benz’s mid-size W123 models—the substantially revised and very different-looking W124 models would follow for 1986.

For 1985, the 300CD Turbo powertrain continued to be the fuel-injected 125 bhp 3.0 liter/183 ci inline five turbodiesel connected to a four-speed automatic transmission. At about 3,360 pounds, these were not fast cars—Car and Driver recorded a 0-60 time of 12 seconds. Fuel economy was 22 city/25 highway by the day’s standards—19/23 by today’s measures. With the 21.1-gallon fuel tank, the driver of a 300CD could expect 400 to 445 miles of range with a 10% reserve.

Standard Equipment & Options

The base price for the 300CD Turbo was a non-trivial $35,220—about $108,600 in today’s dollars or almost twice what a 2025 CLE 450 4MATIC coupe goes for. You did get a lot of standard equipment for a 1985 vehicle: power steering, power brakes, halogen headlamps, halogen fog lamps, and 195/70HR14 tires (a size still readily available) on 14-inch light alloy wheels were all included. Inside, power windows, power door locks, cruise control, intermittent windshield wipers, eight-way power front bucket seats, electronic climate control, and an AM/FM stereo with cassette player and power antenna were standard.

There were few options on the 300CD Turbo: leather upholstery, an anti-theft alarm system ($335), and a power sunroof (optional at no extra cost) were available.

The View From 2025

W123 models definitely have a following, especially the relatively rare coupes and the 300TD wagons. According to Hagerty’s valuation tools, all the money for a 1985 300CD in #1/Concours condition is $67,000, with a more normal #3/Good condition car going for $25,700. 300CDs sometimes show up for sale in the Hemmings Motor News classifieds, on eBay Motors, and on Bring a Trailer, often with mileage well over 200,000.

I like these coupes, with their smooth hardtop lines and their reasonable size. Make mine Astral Silver Metallic, I think.

Other Mercedes-Benz models I have written about include the 1980 450SL convertible, the 1981 380 SEL sedan, the 1985 380SL convertible, the 1986 560SEC coupe, the 1986 560SL convertible, and the 1989 560SL convertible.
