The Mercedes-Benz W126 S-Class is often hailed as one of the finest luxury cars ever produced, and for good reason. These vehicles strike a perfect balance: modern enough to provide a satisfying driving experience, yet classic enough to avoid the pitfalls of overly complex modern technology. Their engineering and design are remarkably logical, making them accessible even to DIY mechanics. This particular article shines a spotlight on a remarkable 1985 Mercedes 500SEL located in Fort Worth, Texas, boasting a unique and desirable factory option. While US-market models had limited customization, this one possesses a feature that truly sets it apart.
Performance and Specifications: US vs. Euro Specs
When considering a 1985 Mercedes 500sel, enthusiasts often weigh the differences between US and European specifications. Ideally, a Euro-spec 500SEL or a US-spec 560SEL might be preferred by some due to performance considerations. US-bound 500SELs were modified to meet Department of Transportation (DOT) and Environmental Protection Agency (EPA) regulations, resulting in increased weight and reduced engine output. The US-spec 5.0-liter M117 V8 engine delivered a modest 184 horsepower. However, its 247 lb/ft of torque ensured adequate acceleration, achieving 0-60 mph in the low to mid 8-second range, with a top speed exceeding 134 mph. In contrast, European versions of the 5.0-liter M117, and the larger 5.6-liter variant, boasted 0-60 mph times of 6.5-7.2 seconds and top speeds approaching 150 mph. Despite the power difference, the US-spec 500SEL remains a comfortable and capable cruiser. Ultimately, the condition and optional features of a specific car often outweigh minor discrepancies in engine output.
Addressing Common W126 Styling Points
Several aspects of the 1985 Mercedes 500SEL’s styling often become points of discussion for enthusiasts. Firstly, the US-spec headlights are a frequent target for modification. Many Mercedes-Benz aficionados find the sealed-beam headlights on US models, including the W126, to be aesthetically unappealing compared to their European counterparts. Given that aerodynamics were a key consideration in the W126 design, the blocky US headlights can appear out of place. Upgrading to European-spec headlights is a common and relatively straightforward modification, typically costing around $500 for parts and DIY installation.
Secondly, the original 14-inch wheels often look undersized by modern standards, and tire availability in this size is limited. Upgrading the wheels not only enhances the car’s appearance but also improves handling and tire selection. Purists might opt for OEM-style 15-inch “bundt” alloy wheels, readily available on the used market for $800-$1200 per set. More budget-friendly and larger options also exist, such as 16-inch 8-hole style wheels, offering a good balance of cost and aesthetics. Later W126 15-inch 16-hole alloy wheels are another popular upgrade. Any of these options will improve handling and expand tire choices while better filling the wheel arches. Lastly, while replacing the US bumpers with slimmer European versions can further enhance the car’s looks, it’s a more involved and costly modification that may not be worthwhile for all owners.
Interior Features and the Special Rear Seating
The 1985 model year marked the introduction of standard driver’s side airbags and anti-lock brakes for the 500SEL, significant safety advancements for the time. A well-maintained 1985 500SEL should have these systems in good working order. The interior of this particular car features handsome burled walnut wood trim, a desirable black dashboard and steering wheel, and cream beige leather upholstery. The condition appears consistent with the car’s relatively low mileage of 70,000 miles. Notably, this 500SEL is equipped with the optional front sport seats, which offer more bolstering and a narrower profile compared to the standard, more relaxed seats found in most W126 sedans (though standard in SEC coupes). These sport seats retain the 500SEL’s standard seat heaters, a highly valued feature. The car also retains its original Becker stereo, which can be upgraded to include iPod connectivity for modern convenience without sacrificing the classic look.
However, the true highlight of this 1985 Mercedes 500SEL lies in its rear passenger compartment. This car was optioned with the “executive” package, featuring individual, heated, and reclining rear seats, eliminating the center rear seat. This configuration prioritized passenger comfort and provided space for business accoutrements of the era, such as briefcases or early mobile phone systems. This rare and luxurious option is unlikely to be seen on many W126s at typical car shows. Even rarer upholstery choices for this option included velour (prone to wear) or buffalo leather, a distinctive suede-like leather reserved for top-tier luxury sedans like this and the BMW 745i.
The Enduring Appeal of the W126 S-Class
While the 1985 Mercedes 500SEL, even with its rare options, may not reach the collectible status of a Gullwing, its appeal to enthusiasts is undeniable. With over 800,000 W126 models produced, sedans, in particular, are unlikely to become extremely valuable. However, the W126 S-Class, especially in well-maintained condition, offers a compelling blend of classic luxury, robust engineering, and surprising reliability even decades after production. Both gasoline and diesel versions are known for their longevity, often exceeding 400,000 miles with proper maintenance. Regular oil changes and attention to minor issues can ensure a W126 serves as a dependable daily driver for years to come. For those with an appreciation for understated luxury and solid German engineering, a 1985 Mercedes 500SEL, particularly one with unique options like this, represents a compelling classic car ownership experience.
