Description
Mercedes-Benz 300 D | 1977
Highlights:
- Service history and mileage documentation available
- Dry climate survivor
- Five-cylinder diesel engine with manual transmission
- Historical Interest Certificate included
The seller offers for sale this 1977 Mercedes-Benz 300 D, a well-preserved diesel-powered sedan. This vehicle features a 3.0-litre five-cylinder diesel engine paired with a manual gearbox—an uncommon combination that emphasizes both fuel efficiency and mechanical engagement. According to the seller, this 300 D is supported by a service history and odometer documentation, and it holds a Historical Interest Certificate, underlining its significance as a collector-grade vehicle.
With approximately 200,000 km on the odometer, the vehicle comes with a valid inspection.
The paint and bodywork are rated as good, with only minor scratches noted. The vehicle’s dry Portuguese climate and consistent maintenance have helped preserve its structural integrity, and the undercarriage is reported to be clean and solid. The sunroof is currently non-operational—a deliberate choice by the seller due to concerns about water ingress, a known issue with this model.
Inside, the 300 D features a clean, minimally worn interior that reflects careful ownership. The seats are intact and comfortable, and major controls and displays are functional.
The W123-series Mercedes-Benz, introduced in 1976, quickly earned a reputation as one of the most reliable and well-engineered cars of its era. Known for their durability, particularly in diesel form, these models became legendary in both private and commercial use across Europe, Africa, and the Middle East. The 300 D offered a balance of comfort, efficiency, and longevity, often exceeding 500,000 km with regular servicing.
While the W123 chassis became synonymous with Mercedes-Benz’s bulletproof reliability, the 300 D models in particular have gained a cult following for their ability to outlast almost anything else on the road. Their simplicity, parts availability, and robust diesel engines make them both collectible and usable, even today.
This example, with its historical certification, manual gearbox, and documented history, stands out as a rare find. It’s an ideal choice for the enthusiast looking for a dependable, characterful classic that can be used on a regular basis or cherished as part of a growing collection.
