My '03 Adrenalin has cloth seats and unpainted lower cladding. I think the Adrenalin package for '03 included the upgraded stereo with amplifier and subwoofer, different step bars, different wheels (thumbprint?) with different center caps, "Adrenalin" emblems, leather steering wheel, and larger tires. I think the remainder of the options (front tow hooks, rear A/C and sound system controls, roof rack, floor mats, overhead console, etc.) were part of the XLT Premium Package that is on my truck.
