The E34 also included the high-performance M5 model, powered by the S38 inline-six engine.

🏆 Awards & Recognition

Car And Driver 10Best:

The E34 5 Series was a frequent recipient of Car and Driver's '10Best' list during its production run, lauded for its balance of luxury and performance.

European Car Of The Year:

While not winning outright, the E34 consistently placed highly in European Car of the Year competitions and received numerous accolades from automotive press worldwide.

Reliability Perception:

While generally well-engineered, E34s are complex machines requiring diligent maintenance. Reliability can be excellent when properly maintained, but can suffer with neglect due to age and the availability of specialized parts.
