What owners say
5 Series
Overall
Sentiment is highly polarized and generation-dependent. For the latest generation (G60, circa 2024-2025), initial owner feedback is sharply negative, with strong criticism directed at its excessive physical size, the near-total removal of physical controls in favor of digital interfaces, and perceived lack of driving satisfaction, particularly in lower-powered variants like the 520d. In contrast, feedback on the preceding F10 (circa 2010-2017) and G30 (circa 2017-2023) generations is generally positive, with owners expressing love for their vehicles, praising them as excellent daily drivers that balance comfort, performance, and a high-quality, driver-focused interior.
Best version to buy
For the F10 generation, the 535i with the N55 inline-six engine is specifically recommended over V8 models (550i, 750i) due to its superior reliability and lower maintenance costs, making it a smarter choice for used buyers. For the G30 generation, the 530i is noted as having strong torque and not being slow.
Known issues
- Excessive size and lack of physical controls (G60 generation): criticized as too large and unsatisfying due to digital switches for even basic functions like airflow vents. Frequency: recurrent.
- High maintenance costs and unreliable engines (specific to older V8 models): the N63 V8 engine (in 550i/750i) is regarded as one of BMW's most unreliable, requiring expensive repairs.
- Digital interface and haptic feedback concerns (newer generations): buttons may not work in very cold weather (below -10°C / 14°F), failing to recognize touch with gloves. Frequency: isolated.
E-class
Overall
\nSentiment is mixed and heavily dependent on the specific generation and ownership context. 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.
Known issues
- \nHigh maintenance and repair costs: Includes expensive routine servicing, premium fuel requirement, costly parts (e.g., wiper motor, brake lines, air suspension components), and labor.
