The Mercedes 560 Sec. Just the name evokes images of timeless luxury, powerful performance, and classic German engineering. This grand coupe, a pinnacle of the W126 generation, remains a highly sought-after classic car for enthusiasts and collectors alike. Its blend of elegant design, robust build quality, and V8 power offers a driving experience that’s both refined and exhilarating. If you’re considering adding a Mercedes 560 SEC to your garage, or are simply captivated by this iconic vehicle, this guide provides essential insights to navigate the buying process and ensure you find a well-preserved example.
What to Look for When Purchasing a Mercedes 560 SEC
Embarking on the journey to own a Mercedes 560 SEC requires patience and a discerning eye. The market offers a variety of cars, and taking your time is crucial to securing a truly exceptional vehicle.
Take Your Time and Be Patient: Don’t rush into a purchase. The beauty of the classic car market is that desirable models like the Mercedes 560 SEC are consistently available. Waiting for the right car in the right condition is far more rewarding than settling for the first one you encounter.
Explore the Options and Features: The Mercedes 560 SEC was offered with a range of luxurious options, enhancing its exclusivity. While rear seating configurations were more common in sedans, some coupes were also specified with the optional four-place rear seating. Consider features like metallic paint, which adds depth and richness to the car’s lines. Velour seats, though rare in the US market, offer a unique and plush interior experience. Furthermore, look out for less common but highly desirable options such as front seat lumbar support and the electric rear window sunshade.

Color palettes for the Mercedes 560 SEC were diverse and sophisticated, ranging from classic gloss black and pearl black to distinguished cabernet, lapis blue, and cream. Signal red, gold, silver, anthracite (gunmetal gray), and smoke silver were also popular choices, ensuring a color to match every taste. Notably, models from 1986 onwards generally share similar equipment levels up to 1991, with key updates being the introduction of dual airbags around 1989 and optional ASR (Acceleration Slip Regulation) in later years. While ASR can be a useful feature, it’s not considered essential for enjoying the 560 SEC driving experience.
Where to Find the Best Examples: For those seeking the finest Mercedes 560 SEC examples, Southern California, particularly Los Angeles, stands out as a prime hunting ground. The region’s climate is exceptionally kind to classic cars, minimizing rust and preserving bodywork. The sheer volume of S-Class Mercedes originally sold and maintained in Southern California means a greater selection and potentially more competitive pricing. The “staff car” reputation of the S-Class in this region further contributes to a market rich with well-maintained vehicles.
Essential Pre-Purchase Checks: Before committing to a Mercedes 560 SEC, thorough due diligence is paramount. Always request a Carfax report to uncover any accident history or title issues. Obtain a Vehicle Master Inquiry (VMI) from a Mercedes-Benz dealer; this report details the service history performed at official dealerships, providing valuable insights into the car’s maintenance. Crucially, arrange for a comprehensive pre-purchase inspection by a qualified Mercedes-Benz mechanic specializing in classic models.
Identifying Potential Problem Areas: While renowned for their robustness, Mercedes 560 SEC models are not immune to age-related issues. Be particularly attentive to the following:
-
Air Conditioning: The air conditioning system is a known weak point in these cars. If the AC is not functioning correctly, factor in a potential repair cost of around $2000, as fixing it can be complex and expensive. Even a seemingly minor issue could escalate into a significant repair bill.
-
Becker Radio: The original Becker radios, while period-correct, are often unreliable and technologically outdated. Many owners opt to replace them with modern aftermarket units offering enhanced sound quality and features like CD players or Bluetooth connectivity.
-
Power Windows and Door Locks: The vacuum-operated system for power door locks and windows can develop leaks and malfunctions over time. Test all windows and door locks thoroughly during your inspection.
-
Radiator: The original radiators are susceptible to upper hose neck breakage, especially if non-Mercedes-Benz coolant has been used. These radiators are constructed with plastic components that can degrade with incompatible coolants. Consider the radiator as a potential consumable item, especially on cars with higher mileage or unknown maintenance history.

500 SEC vs. 560 SEC: Engine Performance and Model Years
Understanding the difference between the Mercedes 500 SEC and 560 SEC is crucial for making an informed buying decision. While the earlier 500 SEC models (1984-1985) are still desirable coupes, they are notably less powerful than the 560 SEC (1986-1991). The 560 engine delivers significantly enhanced performance, making it the preferred choice for enthusiasts seeking the full Mercedes-Benz grand touring experience.
If budget is a primary concern, a 1985 500 SEC might represent a more affordable entry point. However, be aware that the performance difference is substantial. The introduction of the 560 engine in 1986 coincided with the virtual cessation of the gray market for Mercedes-Benz in the US. Therefore, virtually any Mercedes 560 SEC from 1986 to 1991 will be a US-market model, simplifying parts availability and service.
Budgeting for Your Dream 560 SEC Coupe
Setting a realistic budget is essential when pursuing a Mercedes 560 SEC. Prices vary widely based on condition, mileage, model year, and options. On the lower end of the spectrum, around $10,000-$12,000 might secure a presentable 1985 500 SEC with higher mileage. Conversely, pristine, low-mileage examples, particularly later 560 SEC models, can command significantly higher prices. A near-concours 1990 560 SEC with exceptionally low mileage fetched a remarkable $48,000 in the California market, demonstrating the premium value of top-tier examples.
The general consensus among classic car enthusiasts is to invest in the best condition Mercedes 560 SEC you can afford. Spending more upfront for a well-maintained car can often save you considerable expense and headaches in the long run, mitigating the risk of immediate and costly repairs. A meticulously maintained, stock condition car, ideally with comprehensive service records and ownership history, represents the most prudent purchase.
Verifying Authenticity and History
Beyond Carfax and VMI reports, further steps can enhance your due diligence. Contact a Mercedes-Benz dealership and request the original window sticker using the car’s VIN (Vehicle Identification Number). This document confirms the original factory options and the delivering dealer. Scrutinize the service records and, if possible, attempt to contact the mechanics or previous owners who maintained the car. Personal accounts can provide invaluable insights into the vehicle’s history and care. As previously mentioned, Los Angeles offers a concentration of well-maintained Mercedes 560 SEC models, often boasting comprehensive service histories and benefiting from the region’s favorable climate.
Maintaining Your 560 SEC for Years to Come
Owning a Mercedes 560 SEC is a rewarding experience, but it necessitates a commitment to proactive maintenance. Adhering to a rigorous maintenance schedule is crucial to preserving its reliability and longevity. Consider these maintenance intervals as a baseline for optimal care:
-
Oil Changes: Every 3,500 miles, especially under dusty or city driving conditions.
-
Air and Fuel Filters: Replace air filters and both fuel filters approximately every 15,000 miles.
-
Automatic Transmission Fluid: Change transmission fluid every 15,000 to 30,000 miles, depending on driving style and conditions.
-
Brake Fluid Flush: Perform a brake fluid flush annually or every 12,000 miles. The stringent interval reflects Mercedes-Benz’s engineering for high-performance braking.
-
Rear Differential Fluid: Change rear differential fluid every 30,000 miles, using Mercedes-Benz limited-slip differential fluid for models equipped with LSD.
-
Spark Plugs: Replace spark plugs every 15,000 to 30,000 miles, depending on your preference and driving habits.
-
Power Steering Fluid and Filter: Renew power steering fluid and filter every 20,000 to 30,000 miles, even though it’s not explicitly listed in older owner’s manuals. This preventative measure can extend the life of the power steering pump.
-
Hydraulic Rear Suspension Fluid: Change the fluid in the hydraulic rear suspension system every 30,000 miles to prevent potential issues and maintain optimal ride quality.
-
Motor Mounts: Inspect motor mounts around 50,000 miles and replace as needed.
-
Wheel Alignment: Check wheel alignment every 12,000 miles or as needed, especially if you notice uneven tire wear.
While this maintenance schedule might seem extensive, it’s a testament to the proactive care required to keep a Mercedes 560 SEC in peak condition. Preventative maintenance is an investment that pays dividends in reliability and driving enjoyment. Conversely, neglecting maintenance on these cars can lead to substantial repair bills.
Bodywork on a Mercedes 560 SEC is notoriously expensive to restore to factory standards. Therefore, prioritize cars with original, well-preserved bodywork and avoid examples requiring significant cosmetic repairs.
Originality vs. Modifications
For most collectors and enthusiasts, a Mercedes 560 SEC in stock, original condition is the most desirable. While some aftermarket modifications, such as lowering springs or AMG exhaust systems, can enhance the car’s aesthetics or sound, they can also detract from its long-term value and originality. Unless modifications are professionally executed and period-correct, it’s generally advisable to seek out a 560 SEC that remains true to its factory specifications.
Ensure that the car includes its original tool kit, first aid kit, and spare tire – these details contribute to the car’s completeness and collectibility. While opinions vary on modifying the suspension for enhanced handling, Mercedes-Benz engineered these cars to perform optimally with the factory-specified springs, tires, and wheels.
Conclusion: Embracing the Mercedes 560 SEC Experience
Purchasing a Mercedes 560 SEC is more than just buying a car; it’s investing in a legacy of automotive excellence. By exercising patience, conducting thorough research, and prioritizing condition and maintenance history, you can find a 560 SEC that will provide years of driving pleasure and classic car ownership satisfaction. Embrace the journey, enjoy the powerful elegance of this iconic coupe, and become part of the enduring Mercedes-Benz 560 SEC story.
