What Problems Does the 1987 Mercedes-Benz 300 Have?

The 1987 Mercedes-Benz 300, part of the robust W124 E-Class, is generally known for its exceptional long-term reliability. However, like any vehicle of this age, specific issues can arise. One frequently reported problem is related to the head gasket, particularly on the gasoline inline-six engines (M103 found in the 300E). Early signs might include coolant loss or white smoke from the exhaust. While not a recall item for this specific year, it's a common repair that can be costly if neglected.

Another area to watch is the electrical system. The wiring harnesses, especially those made with earlier types of insulation, can become brittle and degrade over time, leading to intermittent electrical gremlins. This can affect everything from window motors to dashboard lights. Owners often report issues with the vacuum-operated central locking system and power windows failing.

The diesel variants (300D) are typically more mechanically simple and robust. However, the pre-combustion chambers can sometimes develop cracks, leading to rough running and increased fuel consumption. The glow plug system is also a regular maintenance item.

Rust is a perennial concern for vehicles of this vintage, especially in climates where road salt is used. Common areas for rust include the wheel arches, rocker panels, around the sunroof, and the undercarriage. Thorough inspection is crucial.

The headliner material is also known to sag and deteriorate over the years due to the adhesive failing. This is often a cosmetic issue but can be an annoyance. While there weren't widespread, catastrophic recalls for the 1987 model year that impacted its core reliability, routine maintenance and proactive addressing of minor issues are key to maintaining these vehicles. The complexity of some components means that specialized Mercedes-Benz mechanics are often preferred for repairs, which can add to the overall cost of ownership.

How long will the 1987 Mercedes-Benz 300 last?

With diligent maintenance, 1987 Mercedes-Benz 300 models are renowned for their ability to reach and surpass 200,000 miles, with many examples regularly exceeding 300,000 miles. The diesel variants, in particular, are celebrated for their longevity. The underlying engineering and robust construction contribute significantly to this long service life. However, over time, components like suspension bushings, fuel pumps, and cooling system parts will inevitably wear and require replacement. Proactive maintenance is key; addressing small issues like minor coolant leaks or electrical quirks before they escalate prevents more significant, costly failures and ensures the vehicle continues to offer reliable service for many years.

What Technology & Safety Features are Included?

The 1987 Mercedes-Benz 300 embodies the era's approach to automotive technology, prioritizing safety and functionality over flashy digital interfaces. Built-in tech was focused on a premium driving experience. Standard entertainment typically consisted of an AM/FM radio with a cassette player, often with a decent speaker system for the time. Power windows, power locks, and cruise control were standard conveniences.

Driver-assistance features in 1987 were rudimentary by today's standards. The most significant was the standard Anti-lock Braking System (ABS), which was a pioneering safety technology at the time, significantly improving braking control during emergency stops on slippery surfaces. The car's robust chassis and sophisticated independent suspension also contributed to a stable and predictable driving experience.

Safety was a paramount concern for Mercedes-Benz. The W124 chassis, including the 1987 300 models, was engineered with a strong safety cell, crumple zones, and reinforced pillars. Features like seat belts (with pre-tensioners on later iterations of the W124, though perhaps not standard on all 1987 models), padded interior surfaces, and a well-designed dashboard contributed to occupant protection. The exterior lighting system was also designed for good visibility.

Optional features could enhance the comfort and convenience, such as automatic climate control, a power sunroof, heated front seats, and sometimes an upgraded stereo system. While specific official crash-test ratings for the 1987 model year in the US might not be as readily available or comparable to modern standards (as ratings systems have evolved), the W124 platform consistently demonstrated strong safety performance for its time, earning a reputation for being one of the safest sedans available. Mercedes-Benz vehicles of this era were tested extensively internally to meet rigorous safety standards.
