nice quiet ride. very smooth. we take the truck for family outings, while the suv sit in the garage. i've learned to drive easy to maximize mileage using afm, but would like it to stay in 4cyl at higher speeds/rpm. average is 17.1 on computer. had one problem with pass lock not locking/unlocking. it was fixed under warranty.
active fuel management. packages with 20" wheels, steering wheel controls,dual ac.
more gears. better afm system, or a manual mode for 4 or 8 cyl
