Inside, the ZHP is differentiated from a standard E34 3 Series with cloth and Alcantara sport seats as well as an Alcantara-wrapped steering wheel. Silver Cube aluminum trim completed the sporty look and the engine was modified to rev 300 rpm higher than the standard car, which is reflected on the instrument panel. Aside from these changes, the ZHP boasts typical E46 trimmings, which do feel dated by today's standards. A base radio was standard but BMW offered a navigation head unit. We suggest ripping out the stock head unit and replacing it with a look-a-like system that appears like a factory unit but adds a touchscreen and modern features.
