BMW Z4 (G29) Common Problems & Reliability
The latest Z4 (G29), developed alongside the Toyota Supra, returned to a fabric soft-top and shed significant weight, making it much sharper to drive than the E89. Positioned as a dedicated, focused sports car, it offers brilliant B-series engines, particularly the B58 straight-six in the M40i. It is highly praised in the UK for its fantastic interior tech, excellent handling, and robust reliability, suffering mainly from minor software glitches rather than mechanical flaws. It perfectly suits driving enthusiasts wanting a modern, fast, and highly capable roadster with cutting-edge infotainment.
