The Mercedes-Benz W126 S-Class is celebrated among automotive enthusiasts as one of the finest luxury vehicles ever manufactured. These cars strike a perfect balance, offering a sophisticated driving experience while remaining accessible for maintenance, even for those less mechanically inclined. Their engineering is remarkably logical and robust, a testament to Mercedes-Benz’s commitment to quality. Today, we’re focusing on a particularly appealing model: the Mercedes 500 Sel.

While enthusiasts might lean towards the European-spec 500 SEL or the US-spec 560 SEL for enhanced performance, the US-spec 500 SEL still holds significant appeal. Due to US regulations, modifications for DOT and EPA compliance slightly reduced power and increased weight. The US-spec 500SEL’s 5.0-liter M117 V8 engine produced around 184 horsepower. However, its 247 lb/ft of torque ensured respectable acceleration, reaching 60 mph in the low to mid 8-second range, with a top speed exceeding 134 mph. In contrast, European versions and the 5.6-liter M117 engine boasted 0-60 mph times of 6.5-7.2 seconds and top speeds approaching 150 mph. Despite these differences, the US-spec Mercedes 500 SEL remains a comfortable and capable cruiser. Ultimately, the condition and specific options of a particular car can often outweigh minor variations in engine output.

However, some aspects of the US-spec models might benefit from upgrades to align with European aesthetics and performance. One common point of contention is the US-spec headlights. Many Mercedes-Benz aficionados find the sealed-beam headlights detract from the W126’s aerodynamic design. Replacing these with European-spec headlights can significantly enhance the car’s appearance and is a worthwhile upgrade for enthusiasts.

Another area for potential improvement is the wheel size. The standard 14-inch wheels on the US-spec Mercedes 500 SEL can appear undersized by modern standards, and tire availability in the correct size may be limited. Upgrading to 15-inch or 16-inch wheels not only enhances the car’s stance but also provides a wider selection of modern tires, improving handling and ride quality. Original Equipment Manufacturer (OEM) style 15-inch “bundt” alloy wheels are a popular choice for purists, maintaining a classic Mercedes look. Alternatively, 16-inch 8-hole style wheels offer a more contemporary touch while still complementing the W126 design. While European bumpers offer a sleeker profile, the cost and effort of replacement might outweigh the visual benefits for some owners.

The 1985 model year marked a significant step forward in safety for the Mercedes 500 SEL, introducing driver’s side airbags and anti-lock brakes as standard features. A well-maintained example from this year should have these systems in good working order. Inside, the burled walnut wood trim exudes classic luxury, and the sought-after combination of a black dashboard and steering wheel paired with a cream beige leather interior creates an elegant and timeless ambiance. The often-desirable sport seats in this model offer enhanced bolstering compared to the standard seats, providing a more supportive driving experience while retaining features like seat heaters. The presence of the original Becker stereo system adds to the car’s authentic vintage charm, and these units can even be upgraded with modern iPod connectivity for enhanced audio options.

The true highlight of certain Mercedes 500 SEL models, and a feature that sets them apart, is the rare “executive” four-place seating option. This luxurious upgrade replaces the standard rear bench seat with individual, heated, and reclining rear seats, eliminating the center seating position. This configuration was designed for ultimate rear passenger comfort and convenience, offering a prestigious and exclusive experience. Finding a W126 S-Class with this option is uncommon, making it a notable feature for collectors and enthusiasts. Even rarer upholstery options like velour or buffalo leather (a suede-like finish) would further enhance the exclusivity of such models, though these materials are less frequently seen today.

While the Mercedes 500 SEL sedan, and W126 models in general, may not reach the collectible status of a Gullwing due to their production numbers, they offer enduring appeal as well-engineered and reliable classic luxury cars. A well-maintained W126, whether gasoline or diesel powered, can serve as a dependable daily driver, often exceeding 400,000 miles with proper care. Regular maintenance, like oil changes and addressing minor issues promptly, ensures longevity. For those seeking a blend of classic Mercedes-Benz luxury, robust engineering, and surprising practicality, the Mercedes 500 SEL remains an excellent choice.
