Gibbs-designed and logoed sport leather/suede seats are also available in either two-row ($1450) or three-row ($1850) configurations. Our truck had a $1250 brake package (which has to be reengineered for 2005 due to model changes) that stopped our 2004 version in 128 feet from 60 mph--solid numbers, but not class leading. We also got a taste of the $1900 Infotainment package that features a DVD/MP3/CD head unit with 6.5-inch 16:9 widescreen LCD touch-screen, 400 watts of power, eight speakers, and an amplified subwoofer.

"Thoroughly developed" are the best words to describe the JGP products we've tested. But with three Super Bowls and two NASCAR crowns, we probably should expect nothing less.
