Detailed Explanations

2015-2016 (W212): Proven Reliability, Refined Interior, Strong V6 Engine, Comfortable Ride.

These model years represent the tail end of the W212 generation E-Class. They benefit from years of refinement and have generally proven to be reliable. The 3.0-liter twin-turbo V6 engine is powerful and smooth, offering excellent performance. The interior is well-appointed and comfortable, though the technology is less advanced than later models. The ride quality is typically excellent, making it a great choice for long-distance driving. The W212 E400 offers a compelling blend of luxury and dependability, making it a strong contender for those seeking a pre-owned E-Class.

Aging Technology (compared to later models): While still functional, the infotainment and driver-assistance features of the 2015-2016 E400 models are noticeably less advanced than those found in the W213 generation. This includes a smaller display screen, less intuitive navigation, and potentially fewer advanced safety features like lane-keeping assist and adaptive cruise control.

Potential for high mileage examples: As these models are getting older, it's important to carefully inspect any potential purchase for signs of wear and tear. High mileage can lead to increased maintenance needs and potential repair costs. A thorough pre-purchase inspection by a qualified mechanic is highly recommended.

Possible early signs of corrosion (depending on location): Depending on the climate where the vehicle was driven, some 2015-2016 E400s may exhibit signs of early corrosion, particularly in areas prone to road salt. Carefully inspect the undercarriage, wheel wells, and door seams for any signs of rust before purchasing.

2017-2018 (W213): Modern Design, Advanced Technology, Enhanced Safety Features, Improved Fuel Efficiency, Available as a Coupe, Sedan, Wagon, and Cabriolet.

The 2017-2018 model years mark the introduction of the W213 generation E-Class, a significant leap forward in terms of design, technology, and features. The exterior styling is more modern and aerodynamic, while the interior boasts a more luxurious and technologically advanced cabin. The W213 E400 also benefits from improved fuel efficiency compared to the W212. The wide range of body styles offered – sedan, coupe, wagon, and cabriolet – allows buyers to choose the E400 that best suits their needs.

Potential for early production glitches: As with any new model launch, the 2017 and early 2018 E400s may be more prone to early production glitches. These can range from minor software issues to more significant mechanical problems. It's important to research any recalls or technical service bulletins (TSBs) issued for these model years.

More complex systems mean potentially higher repair costs: The W213 E400 features a more complex array of electronic and mechanical systems compared to the W212. This increased complexity can translate to higher repair costs, particularly for issues related to the infotainment system, driver-assistance features, or engine management system.

Can be more expensive to maintain than W212: Due to the more advanced technology and potential for higher repair costs, the W213 E400 can be more expensive to maintain than the W212 E400. This is something to consider when budgeting for long-term ownership.

2019 (W213 Facelift): Updated Styling, Improved MBUX Infotainment System, Enhanced Driver Assistance Features, Refined Ride Quality.

The 2019 E400 represents a mid-cycle facelift for the W213 generation, bringing with it updated styling, improved technology, and enhanced features. The most notable improvement is the introduction of the MBUX infotainment system, which offers a more intuitive and user-friendly interface. The driver assistance features are also enhanced, providing a more comprehensive suite of safety technologies. The ride quality is further refined, making for an even more comfortable and enjoyable driving experience.

Higher Price Point: The 2019 E400, being the newest of the three model year ranges discussed, commands a higher price point on the used car market. This is due to its updated styling, improved technology, and generally lower mileage compared to earlier models.

Continued complexity leading to potential repairs: While the 2019 E400 benefits from various improvements, it still retains the complex electronic and mechanical systems of the W213 generation. This means that potential repair costs can still be higher compared to the W212 E400.

Some find the MBUX system overwhelming: While many appreciate the advanced features and capabilities of the MBUX infotainment system, some users find it to be overwhelming or difficult to learn. The system has a steep learning curve, and it may take some time to become familiar with all of its functions.
