The E85 Z4 Roadster replaced the popular Z3 in 2003, bringing a stiffer chassis and a controversial new design language. Penned by Chris Bangle, the 'flame surfacing' design was a sharp departure from its predecessor but has aged well, now looking distinctive and modern. The car was offered exclusively with a series of smooth and powerful inline-6 engines, starting with the M54 and later upgrading to the more advanced N52, giving it the performance to back up its aggressive looks.
Collectors appreciate the E85 for its classic front-engine, rear-wheel-drive layout and the feedback from its hydraulic (in early cars) and electric power steering. The 3.0si model, with its 255 hp N52 engine and available 6-speed manual, is the most sought-after variant for its blend of performance and reliability. It represents one of the last analog, naturally aspirated roadsters from BMW, offering a pure driving connection that's missing from many newer cars.
With an average sale price around $14,000, the E85 Z4 market is very accessible. The wide price spectrum reflects condition, mileage, and specification. Base 2.5i automatics occupy the lower end, while pristine, low-mileage 3.0si manual cars command prices north of $30,000. Overall, it's a fantastic value for a modern German sports car.
Buying Tips
- The convertible top's hydraulic motor is prone to failure from water intrusion. Check for smooth operation and signs of moisture in the well behind the seats.
- Like many BMWs of the era, the plastic cooling system components (expansion tank, water pump, thermostat) are a known weak point. Check service history for recent replacement.
- On M54 engines, listen for the 'VANOS rattle' at idle. On N52 engines, the electric water pump is a common failure point that gives little warning.
- Some cars develop 'sticky steering,' where the electric power steering feels notchy just off-center. It's an expensive fix, so test for it carefully.
- Worn suspension bushings, especially the rear trailing arm and front control arm bushings, are common and will negatively affect handling.
Prices for the E85 Z4 Roadster typically range from under $10,000 for higher-mileage examples to over $31,000 for top-spec 3.0si models.
