Buying a Used Mercedes S Class 2013: Essential Checks and Maintenance Tips

Considering a pre-owned luxury sedan? The Mercedes S Class 2013 model represents a pinnacle of automotive engineering and opulent comfort. However, like any vehicle of this caliber, especially when purchased used, it’s crucial to be aware of potential problem areas and maintenance considerations. This guide, drawing from expert advice and owner experiences, will help you navigate the process of buying a 2013 Mercedes S Class, ensuring you make an informed decision.

Key Aspects to Inspect on a 2013 Mercedes S Class

When evaluating a 2013 Mercedes S Class, a thorough inspection is paramount. Given the model year, focusing on specific components known for potential wear and tear is essential. Here’s what to prioritize:

Suspension System: Air Suspension Scrutiny

Mercedes-Benz S Class models are renowned for their air suspension, delivering a supremely smooth ride. However, this sophisticated system requires careful attention in older models. Listen for any unusual noises, especially during colder months, as mentioned by experienced owners. A failing air suspension strut can be a significant expense, but it’s not necessarily “the price of the car” as jokingly suggested in online forums. Independent specialists often offer more cost-effective solutions compared to main dealers for suspension component replacements. Check for consistent ride height and ensure the car doesn’t sag overnight, which could indicate leaks in the system.

Transmission and Differential: Fluid Change is Key

Preventative maintenance is crucial for the longevity of any car, and the Mercedes S Class is no exception. Budgeting for a gearbox and differential oil change is highly recommended upon purchasing a used model, even if the service history is unclear. This proactive step can safeguard against potential future issues and ensure smooth operation. While the cost for both might be around £500 as suggested by some mechanics, it’s a worthwhile investment to ensure these critical components are properly lubricated and functioning optimally.

Service History: Full or Factually Shaky?

A Full Service History (FSH) is often touted as a desirable attribute, but it’s important to scrutinize what this truly means. For Mercedes-Benz, prescriptive servicing requirements, including periodic transmission fluid changes, are vital. Ideally, a FSH from a main dealer provides assurance that these requirements have been met. However, servicing from independent garages, while potentially more affordable, may not always adhere to the same stringent standards. A “back street garage” service history increases the risk of missed services or improper maintenance, potentially leading to higher repair costs down the line.

Maintenance Budget: Thousands, Not Hundreds

Prospective owners of a 2013 Mercedes S Class must be prepared for potentially higher annual maintenance and repair costs compared to more mainstream vehicles. Due to the car’s age, mileage, complexity, and the cost of genuine Mercedes-Benz parts, budgeting in the thousands annually for maintenance is a realistic expectation, rather than just hundreds. Even routine maintenance can be more expensive, reflecting the premium nature of the vehicle.

W221 vs. W222: Identifying the Generation

2013 is a changeover year for the S-Class, marking the transition between the W221 and the newer W222 generation. It’s crucial to identify which model you are considering. The W221 is the older model, while the W222 represents a significant step forward in technology and design. The car in question in the original forum thread was identified as the W221. Knowing the specific model generation is important for understanding potential issues, parts availability, and overall value.

Common Issues: Oil Cooler Seals and ABS Sensors

The older W221 models, like the 2013 variant, can be prone to certain issues. One notable concern is potential oil cooler seal problems, which can be costly to rectify. Additionally, ABS sensors are another area that might require attention. While replacing an ABS sensor can be a relatively inexpensive DIY task, as one owner experienced, failure can impact critical safety systems like ABS, adaptive cruise control, and blind spot warnings.

ULEZ Compliance and Tax Implications

For UK buyers, it’s important to note that older (non-BlueTec) W221 models might not be Euro 6 compliant and could be subject to ULEZ (Ultra Low Emission Zone) charges in certain cities. Furthermore, older vehicles often attract higher road tax compared to newer, more efficient models. These running costs should be factored into the overall ownership budget.

Conclusion: Balancing Luxury with Realistic Expectations

Purchasing a 2013 Mercedes S Class can be a rewarding experience, offering unparalleled luxury and prestige at a more accessible price point than newer models. However, it’s essential to approach the purchase with realistic expectations regarding maintenance and potential repair costs. Thoroughly inspect the suspension, understand the service history, budget for essential fluid changes, and be aware of common issues associated with the W221 generation. By doing so, you can enjoy the sophistication of a Mercedes S Class while mitigating potential financial surprises.
