The Mercedes-Benz C126 series, and particularly the 500 SEC model, enjoys widespread acclaim among automotive enthusiasts globally. A quick online search, across English, German, French, and Japanese sources, reveals a near-universal agreement: the C126 represents Mercedes-Benz at its absolute finest. This remarkable consensus begs the question: is the Mercedes-Benz 500 SEC truly deserving of such praise, or are there overlooked flaws in this celebrated classic?
Introduced in 1981, following the W126 saloon in 1979, the C126 coupé completed the new S-Class range. Mercedes-Benz offered the coupé in two potent V8 variants: a 3.8-liter and the coveted 5-liter. Eschewing smaller six-cylinder engines or diesel options, the C126 was positioned as an exclusive, high-performance two-door grand tourer. While initially available with the 3.8-liter engine, the more powerful 500 SEC didn’t reach the American market until 1984, adding to its allure and anticipation.
The C126’s lineage is proudly displayed in a classic Mercedes-Benz advertisement, tracing the evolution of their top-tier coupés from 1935 to 1982. This visual history underscores the significant growth in size of the C126 compared to its predecessors. The advertisement itself is a testament to Mercedes-Benz’s heritage and their claim as pioneers of the “coupé” name, though historically debated, emphasizes their long-standing tradition of luxury two-door vehicles.
The Ever-Growing Benz Coupé: Dimensions and Power
Mercedes-Benz coupés have consistently increased in size over the decades. The wheelbase of the earlier W111/112 models measured a modest 2750mm. This expanded to 2820mm for the C107 and further to 2850mm for the C126. The subsequent C140 saw another significant increase to 2944mm. This growth trend is mirrored in the width and engine displacement, reflecting the evolving demands for larger, more powerful luxury vehicles.
This featured Mercedes-Benz 500 SEC is an early production model (1981-1985). The 500 SEC engine variant continued after the model’s subtle facelift, while the 380 SEC, primarily intended for the US market, was replaced by the 420 SEC in 1985. The mid-1980s also saw the introduction of the even more luxurious 560 SEC, positioned at the pinnacle of the C126 range. Over its ten-year production run, Mercedes-Benz sold over 73,000 C126 coupés, a remarkable achievement for a prestigious automobile. The 500 SEC was the most popular variant, with over 30,000 units produced, benefiting from its availability throughout the entire production period. The 5.0-liter V8 engine delivers 228 horsepower, propelling this substantial 2.2-ton coupé to a top speed of 210 km/h (130 mph), making it a true Autobahn cruiser built for high-speed комфорт.
Enduring Quality and Rarity on Today’s Roads
Mercedes-Benz vehicles of the 1980s and 1990s were renowned for their over-engineering, contributing to the numerous examples still seen on roads today. While models like the W123, W124, and W201 are frequently spotted, particularly in urban environments like Tokyo, classic S-Class Mercedes coupés, such as the C126, are less common. Among S-Class models, the W126 saloon is more frequently encountered, making the C126 coupé a relatively rare and sought-after sight, especially in comparison to earlier W111 and C107 coupés.
The featured 500 SEC is likely a Japanese market car, evidenced by its period-correct fabric upholstery and the pre-2000 two-digit license plate. These cars were undoubtedly expensive when new, and their substantial size might have steered Japanese buyers towards the more practical E-Class. This exclusivity and original high price further enhance the 500 SEC’s desirability as a classic today.
While the Mercedes-Benz 500 SEC is a large car, the rear seating is somewhat compact, a characteristic common to many Mercedes-Benz coupés. For those prioritizing rear passenger space, the four-door saloon variant is the more practical choice. However, the compromise in rear space is arguably a worthwhile trade-off for the C126 coupé’s superior styling and presence.
Bruno Sacco’s Design Masterpiece: Elegance and Modernity
The four-door W126 saloon is undeniably handsome, but the C126 coupé elevates the design language to another level. The front end, with its low-profile SL-style grille, sans the traditional upright Mercedes star, and the sleek composite headlamps (vastly superior to the US-spec sealed beam units), presents a modern and sophisticated interpretation of Mercedes-Benz design. The rear is similar to the saloon, maintaining a cohesive design language across the W126 range. However, the C126’s most striking feature is its profile, characterized by a smoothly flowing beltline and the pillarless greenhouse – a design masterstroke by the renowned Bruno Sacco, head of design at Mercedes-Benz during this era.
A Minor Nitpick: The Door Handles
If a minor criticism can be leveled against the otherwise exceptional Mercedes-Benz 500 SEC, it might be the door handles. Their design appears somewhat out of sync with the car’s overall sleek aesthetic. A simpler, more understated design, perhaps similar to those used on the W126 saloon, might have been a more harmonious choice. While later facelifted C126 models received color-coded door handles, the original design remains a minor point of contention for some enthusiasts.
Peak Mercedes-Benz Coupé? A Matter of Taste
Is the Mercedes-Benz 500 SEC the pinnacle of Mercedes-Benz coupé design? Objectively, it is an outstanding automobile. Subsequent S-Class coupés, like the C140, arguably became too large, while the preceding C107, derived from the R107 roadster, felt less cohesive in its design. The C126 500 SEC excels through its rational design and engineering excellence. However, for some, including the original author, the earlier W111/112 coupés possess a certain emotional appeal that the C126, with its more clinical perfection, perhaps lacks. Ultimately, while the Mercedes-Benz 500 SEC may not definitively win the “heart,” it undoubtedly commands respect as a logical and beautifully engineered masterpiece of its era.
