Overall
Sentiment is sharply divided, creating a high-value, high-risk proposition. Long-term owner reports for the V6 and V8-powered sedans (often referred to as the BH/ DH platform) are overwhelmingly positive regarding mechanical reliability, comfort, and exceptional depreciation-driven value. These models are frequently praised for their "bank vault" solidity, quiet ride, and luxury features at a fraction of the original MSRP.
Best version to buy
The 2015 Hyundai Genesis 3.8L V6 AWD sedan is specifically highlighted as a "gem," particularly units with the smaller 7.5" infotainment screen. This model year benefits from post-facelift updates, available all-wheel drive, and is noted for its solid build quality, quietness, and high feature content.
Known issues
Overall

For the W212 generation (approximately 2009-2016), owner feedback is generally positive regarding its solid build quality, reliability, and driving experience, with it being described as "pretty reliable" and "one of the best running cars" Mercedes has produced in recent decades. The W213 generation (approximately 2017-2023) receives praise for supreme comfort, refinement, and technology, particularly in plug-in hybrid (PHEV) diesel variants noted for excellent fuel economy.
Best version to buy
\nFor the W212 generation (2009-2016), the 2014-2017 model years are specifically recommended as being "well sorted." The E350 and E400 models with standard suspension (avoiding AIRMATIC air suspension if reliability is a priority) are cited as rock solid. For the W213 generation, the E300de (diesel plug-in hybrid) estate is highly praised for its combination of comfort, refinement, and fuel efficiency.
