Owner's Pitch
"Reliable daily-driver 1985 300D Turbodiesel with $4,000 in recent mechanical work (April 2025). Features the legendary OM617 engine, new tires, and a functioning sunroof. Mechanically refreshed with valves adjusted and new mounts. Great candidate for a cosmetic restoration or a bulletproof commuter. Clean title and smog-exempt in most jurisdictions."

CallDescription
Overview: This 1985 Mercedes-Benz 300D is a reliable daily runner used for commuting and car shows. While it has 344,000 miles, it has been maintained as a solid project with 'good bones' and is a total runner.
Mechanical History: Over $4,000 of mechanical work was completed in April 2025 at 341,000 miles. Service included a 30K service, valve adjustment, differential service, engine/transmission mounts, fuel hoses, vacuum hoses, and a cooling system refresh.
Features and Condition: The interior is in good shape with a working sunroof, heater, and instruments. Recent additions include tires with only 3,000 miles of wear and a single CD radio. The car achieves 23-25 MPG with healthy temps and pressures.
Needs: The vehicle requires body work, including fender repair, light rust treatment, and a paint job. Mechanical needs include an AC compressor changeover, cruise control amplifier, two window switches, and some interior wood facade replacement.
Market Highlights
- The Reliability Premium: The 1985 W123 Mercedes is widely considered one of the most over-engineered vehicles ever built. In 2026, its simple mechanical diesel injection and lack of complex electronics make it highly attractive to enthusiasts seeking a vehicle that can bypass modern 'planned obsolescence'.
- The California Market: Southern California remains the premier market for vintage Mercedes diesels due to the lack of road salt and a high concentration of specialized independent mechanics. A car that has spent its life in this climate avoids the terminal rust that plagues East Coast examples.
- Investment Potential: With the seller having already invested $4,000 into the mechanical 'bones' of the car, the current asking price leaves significant room for a buyer to invest in paint and bodywork. Once cosmetically restored, these models frequently appreciate in value.
