What Problems Does the 1987 Mercedes-Benz S-Class Have?

The 1987 Mercedes-Benz S-Class (W126) is renowned for its robust engineering, but like any older vehicle, it has known issues. A common concern across most W126 models is electrical system problems. The wiring harnesses can degrade over time, leading to intermittent issues with everything from power windows and seats to the climate control and fuel injection. The SRS (Supplemental Restraint System) warning light can also be a persistent nuisance, often due to faulty sensors or control modules. The vacuum-operated central locking system can also become unreliable. On the mechanical front, fuel economy can be a concern, especially with the larger V8 engines, though this is expected for vehicles of this era and size. Some owners report issues with the automatic climate control system, which can be complex and expensive to repair. The ABS system, while advanced for its time, can also develop faults with the modulator or sensors. Regarding specific model years, the earlier W126s (pre-facelift) sometimes had more issues with self-leveling suspension, which was later improved. However, for 1987, most major mechanical and structural components are generally well-sorted. Rust can be a concern, particularly around the wheel arches, rocker panels, and sunroof drains, especially in areas exposed to road salt. Transmission issues are less common but can arise with high mileage without proper fluid changes. While there haven't been widespread, critical recalls specifically for the 1987 model year affecting core components, it is always advisable to check for any open recalls with the VIN. Long-term reliability hinges heavily on meticulous maintenance. These cars were built to last, but neglect will lead to accelerated wear and more expensive repairs. Overall, the W126 is a very reliable car if properly maintained, but potential buyers should be prepared for potential electrical gremlins and the cost of keeping it in top condition.

How long will the 1987 Mercedes-Benz S-Class last?

With consistent and diligent maintenance, a 1987 Mercedes-Benz S-Class can easily surpass 200,000 miles, with many examples well exceeding 300,000 miles. These vehicles are built with exceptional durability, designed for longevity rather than disposability. The chassis and body are robust, though rust can be a long-term weakness in humid or salted environments. Major mechanical components like the engines and transmissions are typically very strong. Weaknesses that appear over time often relate to the complex electrical systems, aging rubber and plastic components, and wear and tear on suspension and braking systems. However, these are generally repairable issues. The key to achieving high mileage and years of service is proactive maintenance, addressing minor issues before they become major problems, and using quality replacement parts.

What Technology & Safety Features are Included?

The 1987 Mercedes-Benz S-Class was a technological marvel for its time, offering a suite of features that set it apart. Standard safety equipment included Anti-lock Braking System (ABS), front airbags (driver and passenger), and crumple zones. The car also featured a robust unibody construction designed for occupant protection. Driver-assistance features were limited by modern standards but included power steering, cruise control, and a tilt/telescopic steering wheel for optimal driver positioning. For comfort and convenience, the S-Class boasted automatic climate control, power windows, power door locks, power-adjustable front seats (often with memory settings on higher trims), and a power sunroof. The entertainment system typically consisted of a high-quality AM/FM radio with a cassette player, often with multiple speakers for a premium audio experience. Optional features added to the luxury and convenience, such as heated front and rear seats, rear-seat power adjustments, a power-operated antenna, and headlight washers. While specific crash-test ratings from official bodies like the NHTSA for this exact 1987 model are not readily available in modern databases, the W126 platform was engineered with an emphasis on safety, incorporating advanced structural designs and passive safety systems that contributed to its reputation as one of the safest cars of its era. Its heavy curb weight and sophisticated chassis also contributed to its stability and ability to withstand impacts. The technology, while not digitized as in modern cars, represented the peak of analog automotive engineering, focusing on reliability and user experience.

1987 Mercedes-Benz S-Class Prices and Market Value

When new in 1987, the Mercedes-Benz S-Class commanded a premium price, with the 300SE starting around $45,000 and the flagship 560SEL reaching well over $70,000. These were substantial sums, reflecting their luxury and engineering. Today, the used market for the 1987 S-Class sees prices vary dramatically based on condition, mileage, and trim level. Well-maintained examples in excellent condition can range from $8,000 to $20,000+, while project cars can be found for under $5,000. Depreciation has been significant over the decades, but for well-preserved models, values have stabilized or even seen modest increases, particularly for the more desirable V8 models. Factors affecting resale value include service history, originality, absence of rust, and overall cosmetic and mechanical condition.

1987 Mercedes-Benz S-Class Cost of Ownership

Owning a 1987 Mercedes-Benz S-Class is generally considered costly. Insurance premiums will vary but are typically higher than for average sedans due to its luxury status and repair costs. Fuel economy, especially with the V8 engines, is poor by modern standards, making it expensive to run daily. Maintenance costs are moderate to high, requiring specialized knowledge and parts that can be pricier. Repairs, particularly for electrical issues or complex systems, can be significantly expensive. While the car's longevity can offset some costs, it is not an economical vehicle to own and operate. It requires a budget for ongoing upkeep to maintain its luxury and reliability.

How Does the 1987 Mercedes-Benz S-Class Compare to Other Sedan?

In 1987, the Mercedes-Benz S-Class (W126) was in a class of its own, but key rivals included the BMW 7 Series (E32), Jaguar XJ6, and Cadillac Brougham. Performance-wise, the S-Class offered strong V8 options that were comparable or superior to its rivals. The BMW 7 Series, especially with its V12 engine in later years, offered a sportier feel, while the Jaguar provided a more classic British luxury experience. Features were a strong suit for the S-Class; it pioneered many safety and comfort technologies. While BMW offered advanced electronics, Mercedes-Benz often excelled in overall build quality and understated luxury. Reliability is where Mercedes-Benz traditionally held an edge over its competitors. The W126 was known for its robust engineering and longevity, whereas the Jaguar XJ6 could be prone to electrical gremlins and rust, and the Cadillac, while comfortable, lacked the European handling finesse. Price-wise, the S-Class was typically at the higher end of the spectrum, competing with similarly priced BMWs and significantly outclassing the Jaguar in initial cost and perceived value. For a better alternative in terms of modern technology and fuel efficiency, one might look at newer luxury sedans. However, if the desire is for classic luxury, unparalleled build quality, and a certain timeless elegance, the 1987 S-Class remains a compelling choice. Similar alternatives in spirit could include the later W140 S-Class for even more technology, or perhaps a well-maintained Lexus LS 400 from the early 1990s, which aimed to emulate the Mercedes-Benz standard of quality.

Final Verdict: Is the 1987 Mercedes-Benz S-Class a Good Sedan?

The 1987 Mercedes-Benz S-Class is ideal for discerning classic car enthusiasts, collectors, or individuals who appreciate timeless design, exceptional build quality, and a luxurious driving experience without the complexity or depreciation of a brand-new luxury car. It is worth buying, but with caveats. Primarily, it should be purchased as a used vehicle. For those considering it, a well-maintained example with comprehensive service records is crucial. Opting for a V8 model (420SEL or 560SEL) offers superior performance and is generally more desirable in the used market. It is best suited for owners who have a passion for vintage German engineering and are prepared for the associated maintenance costs, rather than seeking an economical daily driver.
