Mercedes C-Class C43 W205 Buyers Guide (2016+)

The Mercedes C-Class C43 W205, introduced in 2016, offers a balance of performance and luxury. It features a 3.0-litre turbocharged V6 engine, making it a compelling option for those seeking an entry-level performance saloon with a touch of elegance. This guide will walk you through key factors to consider when buying a used C43 W205, including what to look out for, optional packs, and extras.
Engine and Performance
The C43 W205 is equipped with a 3.0-litre twin-turbo V6 engine, producing 362bhp and 384 lb-ft of torque. This engine provides a satisfying amount of power, capable of accelerating from 0-62mph in just 4.7 seconds. It’s paired with a 9-speed automatic transmission and 4MATIC all-wheel-drive, offering enhanced grip and stability, especially in adverse weather conditions.
When buying a used C43, it's important to verify the engine's service history. Regular maintenance, including oil changes and turbo checks, is crucial for long-term reliability. Some owners report occasional issues with the turbocharger, so it's wise to ensure that the turbo system has been serviced or inspected for signs of wear. Additionally, ask about the car's cooling system, as any signs of coolant loss should not be ignored.
Optional Packs and Extras
The C43 W205 comes with a variety of optional extras and packs that can significantly enhance the driving experience. Here's an overview of the most common options:
AMG Night Package
This package adds sporty touches such as blacked-out exterior trim, darkened headlights, and black 19-inch alloy wheels. If you're after a more aggressive, performance-oriented look, the Night Package is worth considering.
Driver Assistance Package
The Driver Assistance Package includes features like Active Brake Assist, Blind Spot Assist, and Lane Keeping Assist. These advanced safety features are designed to prevent accidents and increase comfort on long drives. If you’re buying a used C43, check if these features are installed, as they can be an invaluable addition.
Panoramic Glass Sunroof
Many C43 models come with the option of a panoramic glass sunroof. This extra brings more light into the cabin, creating a sense of space and openness. It’s a sought-after option for those who like a bright and airy interior. Ensure the mechanism works correctly and that there are no leaks.
Burmester Surround Sound System
A high-quality sound system can make a difference to your daily driving experience. The Burmester surround sound system is one of the best in the class, offering exceptional clarity and bass. If this system is present in the car you’re considering, it’s worth testing to ensure it delivers the sound quality you expect.
AMG Sports Seats
AMG sports seats provide extra support during spirited driving, and they also have an appealing look with contrast stitching. These seats often come with adjustable bolsters for added comfort. Check for signs of wear on the bolsters and upholstery, as these seats can sometimes show damage if the car has been used frequently for aggressive driving.
Performance Exhaust
Some C43 models are equipped with the AMG Performance Exhaust, which enhances the car’s exhaust note, providing a deeper and more aggressive sound. If you prefer a sportier, more distinctive engine note, seek out a model with this option. If your car didn't come with the AMG exhaust, check out our range of exhaust systems for your C43 here!
Common Issues to Be Aware Of
While the C43 W205 is generally a reliable vehicle, there are a few common issues that potential buyers should be aware of.
Suspension Wear
The C43 W205’s suspension is well-engineered, but high-mileage cars may experience wear on the suspension components, particularly the shocks and bushings. If you notice any unusual knocking noises or a harsh ride, have the suspension checked by a qualified mechanic. Need suspension components?
Electrical Gremlins
As with many modern vehicles, some C43 W205 owners report issues with the car’s electrical systems. Problems with the infotainment system, sensors, or the start-stop system have been noted. Ensure all electronic components function properly during your test drive, including the navigation, climate control, and any active safety features.
Braking System
The C43 features high-performance brakes, but like any performance car, they can wear down faster than those on a regular vehicle. Check the brake pads and discs for wear, especially on cars with high mileage, and factor in the cost of replacement if needed. Looking to improve your brakes?

Interior and Comfort
Inside, the C43 W205 offers a luxurious cabin with high-quality materials, but it’s essential to ensure that the interior has been well maintained. Leather upholstery should be in good condition, with no signs of cracking or excessive wear. The cabin is also equipped with a digital display, which should be checked for any signs of malfunction. Ensure that the seats adjust smoothly, and that there are no issues with the heating or cooling functions if equipped.
Running Costs and Fuel Economy
The C43 W205 is a performance-oriented car, so fuel economy might not be its strongest suit. Expect an average of around 25-30mpg, depending on driving style and conditions. Ensure the vehicle has been properly maintained to avoid any surprise costs. Service intervals are typically every 12,000 miles or 12 months, and repairs can be costly, particularly if you need to replace turbo components or suspension parts.
Conclusion
The Mercedes C-Class C43 W205 (2016 and onwards) offers a well-rounded package of performance, luxury, and technology. When buying a used model, it’s important to check for the condition of the engine, suspension, and electrical systems. The optional packs and extras can add significant value, so it's worth considering what’s available on the model you're interested in. With careful attention to these details, the C43 can offer a satisfying driving experience for years to come.
