The Mercedes-Benz W126 S-Class is often hailed as one of the finest luxury vehicles ever produced, and for good reason. These cars strike a perfect balance: they are modern enough to provide a genuinely enjoyable driving experience while retaining a classic charm, free from the overly complex technology that can plague newer vehicles. Their engineering is remarkably logical and robust, making them relatively straightforward to maintain, even for DIY enthusiasts. Among the W126 lineup, the 1985 Mercedes-Benz 500SEL stands out as a particularly interesting model, especially when equipped with rare and desirable options.

The 1985 Mercedes 500SEL, as highlighted in a recent eBay listing, offers more than just the standard luxury expected from the S-Class. While US-market cars had fewer customization options compared to their European counterparts, this particular model boasts one of the most sought-after features of the era.
Performance and Powertrain of the 1985 500SEL
When discussing the 1985 Mercedes-Benz 500SEL, performance is a key consideration. While purists might lean towards the Euro-spec 500SEL or the later 560SEL for outright power, the US-spec 500SEL still holds its own as a refined and capable cruiser. Due to stricter DOT and EPA regulations, the US versions received modifications that added weight and slightly reduced engine output. The US-spec 5.0-liter M117 V8 in the 1985 500SEL produced a respectable 184 horsepower. However, its 247 lb/ft of torque ensured that acceleration remained adequate for the time, achieving 0-60 mph in the low to mid 8-second range, with a top speed exceeding 134 mph.

In contrast, the European 5.0-liter and the 5.6-liter M117 engines delivered significantly more power, resulting in 0-60 mph times of 6.5-7.2 seconds and top speeds approaching 150 mph. Despite the power difference, the US-spec 1985 Mercedes 500SEL provides a smooth and comfortable driving experience, perfectly suited for long journeys and everyday use. For many enthusiasts, the condition and unique options of a specific car outweigh minor differences in engine output, making a well-maintained 1985 Mercedes 500SEL a very attractive proposition.
Addressing Common Issues and Upgrades on a 1985 Mercedes 500SEL
Like any classic car, a 1985 Mercedes 500SEL may require attention to certain areas, particularly concerning aesthetics and handling by modern standards. One common point of contention among Mercedes enthusiasts is the US-spec headlights. The aerodynamic design of the W126 was somewhat compromised by the large, sealed-beam headlights mandated for the US market. Many owners opt to replace these with European-spec headlights, a worthwhile upgrade that significantly enhances the car’s appearance and restores its intended sleek front-end design. This modification, often costing around $500 for parts and DIY installation, is a popular choice for those seeking to refine the look of their 1985 Mercedes.

Another area for potential improvement is the wheels. The original 14-inch wheels on the 1985 Mercedes 500SEL appear small by today’s standards, and tire availability in the correct size can be limited. Upgrading to 15-inch or 16-inch wheels not only improves the car’s stance but also expands tire options and can enhance handling. OEM-style 15-inch “bundt” alloy wheels are a popular choice for purists, while 16-inch 8-hole style wheels offer a slightly more modern aesthetic and are readily available. These wheel upgrades, along with better tires, contribute to improved handling and a more confident feel on the road for the 1985 Mercedes 500SEL.
Interior Luxury and Rare Options of the 1985 500SEL
The 1985 Mercedes-Benz 500SEL marked a significant year with the introduction of standard driver’s airbags and anti-lock brakes, enhancing safety features for this luxury sedan. Inside, the burled walnut wood trim and black dashboard and steering wheel create a classic Mercedes ambiance. The cream beige leather interior of the featured car complements the Cabernet metallic paintwork, presenting a sophisticated and well-maintained cabin. With only 70,000 miles, the interior condition suggests careful ownership and preservation.

The front seats in this particular 1985 Mercedes 500SEL are the optional sport seats, a feature typically found on SEC coupes. These seats offer more bolstering and a narrower profile compared to the standard seats in W126 sedans, providing enhanced support during cornering while retaining the desirable seat heating function. The car also retains its original Becker stereo, a period-correct touch that can be updated with modern connectivity options like iPod integration, blending classic aesthetics with contemporary convenience.

However, the true highlight of this 1985 Mercedes-Benz 500SEL lies in its rear passenger compartment. Equipped with the rare “executive” package, this car features individual, heated, and reclining rear seats, eliminating the center seat for a more spacious and luxurious experience. This option transformed the rear of the 500SEL into a mobile executive lounge, perfect for carrying important documents or, in true 80s style, a mobile phone suitcase. Finding another W126 with this option at a car show would be a rare sight, making this 1985 Mercedes 500SEL truly unique.

The Enduring Appeal of the 1985 Mercedes-Benz 500SEL
While W126 sedans, including the 1985 Mercedes 500SEL, may not reach the collectible status of a Gullwing due to their production numbers, they offer a compelling blend of classic Mercedes luxury, robust engineering, and surprising reliability. A well-maintained 1985 Mercedes 500SEL, even decades after its production, can serve as a dependable daily driver. Both gasoline and diesel versions of the W126 are known for achieving high mileage with proper care, often exceeding 400,000 miles without major engine overhauls. With regular maintenance and attention to detail, a 1985 Mercedes-Benz 500SEL represents a smart entry into classic car ownership, offering a combination of luxury, durability, and distinctive 80s style.
