What owners say
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.
