The inside Hummer H2 is taken from a Pontiac Aztec SUV, specifically the air vents on the instrument panel. Other internal parts are extracted from GM's pickup and SUV parts boxes. Most importantly, it's packed here with plenty of metal flavors, a very bold interior design, coupled with black-and-white gauges used in conjunction with high-end GMC SUVs, and excellent seats. The rearview mirror dims on its own.
