The short answer
Based on available data, the BMW 5 Series comes out ahead of the Tesla Model 3 on power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
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
Overall
Mixed sentiment with a clear generational divide. Long-term owners of earlier models (pre-2024 "Highland") report significant mechanical reliability issues, particularly with suspension components, leading to high out-of-warranty repair costs and diminished resale value. These owners often express frustration with build quality, citing water leaks and inconsistent service experiences.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Discussions indicate a trade-off: the Long Range AWD model is noted for extra mileage and all-weather capability, while the Performance model is desired for its faster acceleration and exterior styling.
