What owners say

Z3

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

  • High maintenance and repair costs: very frequent and emphasized as the defining characteristic of ownership. Includes expensive parts, labor, and the constant need for age-related repairs. Frequency: very frequent.
  • Cooling system failures: a known weak point requiring proactive replacement (radiator, water pump, hoses). Frequency: very frequent.
  • General age-related deterioration: cracking rubber hoses, bushings, interior trim crumbling (especially in sun-damaged convertibles), electrical gremlins. Frequency: very frequent.

Z8

Overall

The sentiment is overwhelmingly positive, with the Z8 consistently described as a special, modern classic, and highly desirable collector's item. It is praised for its unique and futuristic design, hand-built aluminum construction, powerful S62 V8 engine from the E39 M5, and its status as a James Bond hero car. Owners and enthusiasts highlight its excellent driving dynamics, with reports of it outperforming contemporary benchmarks like the Ferrari 360 Modena in acceleration, handling, and braking.

Best version to buy

Insufficient owner data available to distinguish between model years or trims. The vehicle is discussed monolithically as a singular, limited-production model.

Known issues

  • Neon tail light failure: Replacement units are described as costing "friggin' thousands." Frequency: isolated.
  • Cooling system hose failures: A common early-2000s BMW issue; noted that by now this has likely been addressed on most examples. Frequency: isolated.
  • Intermittent engine misfire: One report of an intermittent misfire on a low-mileage example. Frequency: isolated.

The verdict

The BMW Z8 is the better choice for most buyers.

It has more power on its best-equipped version than the BMW Z3, based on the data above. If efficiency matters more to you than outright power, the BMW Z3 is worth a closer look instead.
