Just saw my first one. I will post pic of the window sticker later. the 5.3L RST is about $2600 so this is $2800 more. gets you the 6.2L and 10 speed auto, 170 amp alternator 3.23 gears. this is the price on a 4wd. 2wd pricing may be different. This does not include the 15" rotors/6 caliper brakes which I think are $3150 extra or the performance exhaust which is reportedly 7-10 more hp.
