The short answer
Based on available data, the BMW Z3 comes out ahead of the Hyundai S-Coupe 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 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
Sentiment is mixed and heavily dependent on the specific model year and engine. The vehicle is widely praised for its stylish, sporty design, offering a fun-to-drive nature and a strong value proposition, especially when purchased used. The 3.8L V6 Lambda engine is frequently cited as being incredibly reliable and capable of withstanding significant punishment, with reports of trouble-free operation past 200,000 miles.
Best version to buy
2013 or newer model year with the 3.8L V6 engine. Owners strongly recommend avoiding 2009-2012 3.8L models due to a known oil pressure pump issue that could starve the engine of oil during sharp turns.
