What owners say
M2
Overall
Sentiment is highly positive, with owners praising the M2 as a focused, engaging, and practical performance car that offers a compelling blend of power, handling, and daily usability. The F87 generation (2016-2021) is frequently lauded for its balance, with the original N55-powered model noted for its lighter weight and the Competition (S55) model for its increased power and track capability. The newer G87 generation is acknowledged as a more powerful and technologically advanced successor, though some feedback suggests it feels larger and heavier.
Best version to buy
Insufficient owner data available to declare a single "best" version, as preferences are split by generation and priority. For the F87 generation, the lighter original (OG) M2 is prized for its nimbleness, while the M2 Competition is favored for its S55 engine's increased power and track readiness.
Known issues
- ⚠Manual transmission feel described as "rubbery," "vague," or not particularly special: with long gear ratios, a very light clutch, and rev hang mentioned. Frequency: recurrent.
- ⚠Low-speed drivability quirks: can be jerky in first and second gear, clutch may rattle at bite point, engine power delivery described as "dead" at low revs before becoming "manic" higher in the rev range. Frequency: recurrent.
- ⚠Increased weight in newer generations: the F87 Competition and G87 are noted as being significantly heavier than the original F87, impacting the perception of nimbleness. Frequency: recurrent.
Z4
Overall
Sentiment is highly dependent on the specific generation and powertrain. For the current generation (G29), the Z4 M40i variant receives extremely positive feedback from owners, described as "insanely good," "stupid fast," "incredible power," "balanced," and "the best car I've ever owned." It is praised for its fun factor, driving dynamics, and value proposition, particularly when equipped with a manual transmission. The base 30i variant is considered competent but less memorable, with some reviewers labeling it "forgettable." The previous E89 generation (2009-2016) is viewed more as a comfortable grand tourer or "Palm Beach cruiser," with criticism for feeling heavy and sluggish.
Best version to buy
For the current generation (G29), the Z4 M40i is overwhelmingly recommended as the definitive version. Owners emphasize that the high-output B58 engine transforms the experience, making it "exceptional" and a "real weapon," whereas the lower-powered 30i variant does not leave the same impression.
Known issues
