The interior stitchwork was done by Todd of The Interior Shop in Phoenix, using two-tone gray leather for the bucket seats and door panels. Chris at AZOE pulled the original dash and laminated it with carbon fiber. The steering wheel is a unique CanDo Specialties billet, tribal design. For foot comfort, a plush, gray carpet covers the floor, while the bucket seats are separated by a custom fiberglass waterfall console, constructed and painted by Monster Paint F/X. The gothic flame-embossed gray headliner houses the overhead console. The SnugTop tonneau cover also has an embossed gray inner liner to match the interior headliner.

For some serious audio components in the dash, doors, and center console, Mark cruised over to Erin and Ruddy at Professional Automotive Engineering (PAE) in Phoenix. A Pioneer head unit produces the musical entertainment that is induced by a pair of Memphis thunder amplifiers-one powers the head unit, while the other powers the two booming Memphis 10-inch subwoofers. The system's mid and separate speakers are located in the door panels. After all the components were installed in their appropriate locations, Albert and Tony at Noise Audio in Phoenix wired everything together.

Without a doubt, Mark's Sierra expresses a balance of esthetic styling and productive function. Mark would like to thank his girlfriend, Libby; his brother Adam; and Andy Gullick and Cole Russell. Maybe more of us should take note of the firefighters' saying: You Only Live Once.
