New to the post and am thinking of buying a 07 colorado. (2wd) I want the whole works, leather, power seats, 5 cyl auto. onstar, satelite radio, tire monitor, gas milage display, steering wheel controls.Guess what I need to know is a z71 fully loaded and can it be had with 2wd. Also heard a rumor that 08 colorado may have a v8. Now that would be one heck of a truck. Wanted to swap my 04 silverado in for an 07 but the new body styles look way to big. A half ton looks like a 3/4. Also need ideas on a x-cab verses a 4 dr. 4dr looks neat but really have no need for one. Is the ride different. Any insite to these ???'s will be apreciated.
