The short answer
Based on available data, the Honda S2000 comes out ahead of the BMW Z3 on fuel economy and 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 generally positive, with the Z3 appreciated as a fun, stylish, and engaging classic roadster that offers a distinct character compared to its primary rival, the Mazda Miata. Owners frequently cite its attractive design, the enjoyable driving experience of the inline-6 models, and its status as a more powerful and comfortable alternative to the Miata, especially for taller drivers. However, this is tempered by a very frequent and strong consensus regarding the high and ongoing costs of maintenance and repair, which are described as a significant burden.
Best version to buy
Inline-6 cylinder models (e.g., 2.8L) are strongly preferred over the four-cylinder 1.9L for their superior power, torque, and engine sound. The M Coupe ("Clownshoe") is highlighted by enthusiasts for its unique design and performance, with notes that coupe variants often survive in better condition than convertibles due to less sun damage.
Known issues
Overall
Overwhelmingly positive sentiment, characterized by deep emotional attachment and reverence as a legendary, driver-focused roadster. The vehicle is consistently praised for its "wildly revving" high-RPM engine, exceptional balance, bespoke chassis, and engaging driving dynamics.
