So, you’re on the hunt for a classic Mercedes-Benz 560 SEC, perhaps even dreaming of finding that elusive ’89 model year, possibly with a touch of AMG magic? You’re in the right place. The 560 SEC is a timeless grand tourer, and landing a good one requires patience and a keen eye. This guide, derived from seasoned enthusiasts, will steer you through the crucial aspects of buying a 560 SEC, ensuring you drive away with a gem, not a project.
Patience is Your Best Ally
Don’t rush into a purchase. The market is populated with 560 SECs, and taking your time will significantly increase your chances of finding a well-maintained example. Consider the options these cars offered: luxurious 4-place rear seating in sedans, elegant metallic paint finishes, and plush velour interiors (though less common in the US market). Other desirable, albeit rarer, options include front seat lumbar support and the sophisticated electric rear window sunshade. When it comes to colors, you’ll find a spectrum, from classic gloss black and pearl black to rich cabernet, sophisticated lapis blue, and timeless white, cream, signal red, gold, silver, anthracite (gunmetal gray), and smoke silver. Remember, models from 1986 onwards generally share similar equipment levels through 1991, with dual airbags becoming standard in ’89 and ASR (Acceleration Slip Regulation) appearing around ’91. ASR, while advanced for its time, isn’t necessarily a must-have feature for many enthusiasts.
Location, Location, Location: Southern California Advantage
If you’re looking for the best selection of well-preserved, rust-free 560 SECs, Southern California, particularly Los Angeles, is your goldmine. The sheer volume of cars in this region translates to more competitive pricing and a wider variety to choose from. The S-Class Mercedes was a popular choice in Southern California, meaning the market is relatively saturated, often leading to better deals.
Due Diligence: Paperwork and Inspections
Once you’re serious about a particular 560 SEC, never skip the essential due diligence steps. Always request a Carfax report to uncover any hidden history, and if dealing with a Mercedes-Benz dealer, ask for a Vehicle Master Inquiry (VMI) to reveal the car’s service history performed at dealerships. Crucially, invest in a thorough pre-purchase inspection by a qualified mechanic specializing in Mercedes-Benz vehicles. While 560 SECs are becoming less common on Mercedes dealer lots, remember that their market value has adjusted, making them potentially more accessible than you might think.
Common Trouble Spots: What to Watch For
While generally robust, certain areas are known to be potential trouble spots in 560 SECs:
- Air Conditioning: This is perhaps the most notorious issue. If the AC isn’t blowing cold, factor in a potential repair cost of around $2000. It could be as simple as a fuse, but be prepared for more extensive repairs. Consider a non-functioning AC as a significant price negotiation point.
- Becker Radios: The original Becker radios are often unreliable and considered outdated by modern standards. Many owners opt for aftermarket upgrades like Alpine units with CD changers or more contemporary systems.
- Power Door Locks and Vacuum System: Issues within the power door lock and vacuum systems can occur. Be sure to test all door locks and related vacuum-operated features.
- Radiator Neck Breakage: The original radiators, especially if non-Mercedes coolant was used at any point, are susceptible to upper hose neck breakage. These plastic radiators and their necks weren’t reinforced from the factory. Consider the radiator a consumable item, potentially needing replacement around the 100,000-mile mark, especially as a preventative measure.
Beyond these points, 560 SECs are fundamentally well-engineered and durable if properly maintained. However, parts can be expensive, particularly body components like the aluminum trunk and hood. A stock 560 SEC achieves 0 to 60 mph in approximately 7.0 seconds, offering respectable performance for a grand tourer of its era. While aftermarket modifications like lowering springs and AMG exhaust systems can enhance performance and aesthetics, it’s generally advisable to prioritize a 560 SEC in original, unmodified condition, ideally accompanied by complete service records and stamped maintenance books.
Budgeting Realities: From Entry-Level to Pristine Examples
Your budget will significantly dictate the type of 560 SEC you can realistically acquire. On the lower end, around $10,000-$12,000 might get you an ’85 model (with the slightly less powerful 500 engine) with higher mileage in decent condition. However, for a truly exceptional, low-mileage example, prices can soar. A pristine 1990 SEC with only 7,000 miles sold for a remarkable $48,000 in California, highlighting the premium commanded by top-tier examples.
Generally, with classic cars like the 560 SEC, it’s wise to invest upfront in the best condition car you can afford. A cheaper, seemingly “bargain” car can quickly become costly if it requires extensive immediate repairs. The ideal find is a 560 SEC in stock condition, meticulously maintained by a single fastidious owner, complete with all original books and comprehensive service records.
Unearthing the History: Beyond Carfax
Go beyond the Carfax report. Request a Vehicle Master Inquiry (VMI) from a Mercedes-Benz dealer to uncover dealership service history. Contact Mercedes-Benz USA (using the 1-800-For Mercedes number mentioned in some online resources) to potentially obtain a copy of the original window sticker, providing details of the original dealer and options. Scrutinize the service books and records, and if possible, attempt to contact the mechanics or service centers that previously maintained the car. In some cases, actual repair orders might still be available, offering invaluable insights into the car’s maintenance history.
Maintenance Matters: A Proactive Approach
To ensure the longevity and reliability of your 560 SEC, embrace a proactive and diligent maintenance schedule. Consider these points based on recommendations from experienced Mercedes owners:
- Oil Changes: Every 3,500 miles, especially in dusty or city driving conditions.
- Air and Fuel Filters: (Two fuel filters) Approximately every 15,000 miles.
- Automatic Transmission Fluid: Every 15,000 to 30,000 miles, depending on driving style.
- Brake Fluid Flush: Annually or every 12,000 miles.
- Rear Differential Fluid: Every 30,000 miles, using Mercedes-Benz limited-slip differential fluid for models equipped with LSD.
- Tune-ups and Spark Plugs: New spark plugs every 15,000 to 30,000 miles.
- Power Steering Fluid and Filter: Every 20,000 to 30,000 miles.
- Hydraulic Rear Suspension Fluid (if equipped): Every 30,000 miles.
- Motor Mounts: Inspect around 50,000 miles and replace as needed.
- Wheel Alignment: Every 12,000 miles if necessary.
While this maintenance regimen may seem intensive, it’s preventative and will reward you with a dependable classic car.
Bodywork Caveats and Desirable Features
Steer clear of 560 SECs requiring bodywork. High-quality body repairs on these cars are exceptionally expensive. Cosmetic interior enhancements were introduced starting in 1989. Most models are well-equipped, including ABS and airbags, with dual airbags becoming more prevalent around ’88 or ’89 (identified by the absence of a glove box). Factory options were relatively limited on the 560 SEC, but could include a power rear sunshade, velour upholstery, metallic paint, reinforced seats, and lumbar support. For ’91 models, traction control (ASR) was an option, though not universally desired by enthusiasts. Ensure the car you’re considering includes its original tool kit, first aid kit, spare tire, and jack.
AMG and Modifications: Staying Stock vs. Personalization
While the allure of an AMG-enhanced 560 SEC is undeniable, opinions vary on modifications. Some purists believe Mercedes-Benz engineered these cars to handle optimally in their original configuration. If you’re seeking an AMG variant, be prepared for a potentially higher price and ensure any modifications are professionally and tastefully done. For many, the ideal ’89 Mercedes-benz 560 Sec Amg (or AMG-inspired) is one that retains its classic elegance and factory specifications while benefiting from meticulous care and maintenance, ready to be enjoyed for years to come.
