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.
350Z
Overall
The sentiment among owners is predominantly positive, with the vehicle widely regarded as a reliable, durable, and fun-to-drive sports car. The VQ engine is consistently praised as a "beast" that can "cop a fucking beating without breaking a sweat," with reports of engines lasting well over 250,000 miles with proper care. The platform is described as a "stout design & construction" that is "not considered a problematic used car model." Owners appreciate its dual-purpose capability as both a reliable daily driver and a "full hard track day capable" vehicle.
Best version to buy
Insufficient owner data available to declare a definitive "best" trim or year. However, detailed technical discussions highlight engine variant trade-offs: the early '03-'04 DE engines are noted as solid and economical; the '05-'07 "Rev-Up" DE engines are powerful but notorious for oil consumption; and the '07-'08 VQ35HR engine (also found in the G35) is considered the most stout and powerful NA option.
Known issues
- Electrical system faults: encompassing no-crank/no-start conditions, fuel pump and sensor failures (P0183, P0462 codes), window regulator failures, bizarre turn signal behavior, and Body Control Module (BCM) failures.
- Oil consumption: specifically associated with the '05-'07 "Rev-Up" (DE) engine variant, described as a common and significant problem. Frequency: very frequent.
- Overheating: difficult to diagnose issues potentially related to air in the cooling system, faulty thermostats, or underlying problems not easily identified. Frequency: recurrent.
