I traded my 04 TrailBlazer EXT for a 2008 Z71. It has much better gas mileage. Every feature you could ask for, comfortable ride. Looks great. Added some accesories, wind visors and bug guard. Plenty of leg room in front and back.
Interior design, all controls are easy to access. Storage compartment in center is huge.
Chevy should come out with a removable bed cap. Snugtop has one but it permanently mounts.
