My first automobile was a 1966 Pontiac LeMans which I still have to this day, but I was in need of a truck to haul more around but still have decent power. The body styling on the GMC's does not jump out at you like the Chevy's or Fords etc. I have been extremely pleased with my truck especially in the performance category. After adding a Hypertech power programmer to the truck, the engine output has been amazing. Gas mileage has dropped a bit to about 16/20 but my I don't mind that when I enjoy the performance.
The 40/20/40 seating is a nice feature to have especially with the arm rest that drops down for comfort and storage. Automatically sensored headlights are also a nice feature as well as the digital compass and temperature gauges in the rearview as on the SLE model
More room behind the seats for better storage of bags, etc. Add a 5 Speed manual to the optional 5.3 liter! They could easily take over the performance truck market that Ford and Dodge are competing in.
