There are three available suspensions as well--the standard Z85, the Z71 for off-roading and the sportier ZQ8. The upgraded suspensions require either a crew cab or extended cab; the base model is available with the base Z85 suspension only.
So there are choices to be made, depending on what kind of use the truck will get and where you want to spend your money. All Colorados start with power-assisted rack-and pinion steering, front and side curtain air bags, a tire pressure monitoring system, traction control and GM's OnStar Safe and Sound system. A stereo with CD and MP3 playback is also standard.
From here, options are nearly endless. The Power and Convenience package includes power windows and locks, remote keyless entry, power-adjustable mirrors and an auto-dimming rearview mirror.
All in all, the Colorado can be configured dozens of ways, from the inexpensive, fuel-sipping base model to the top-of-the-line, largest, most powerful crew cab. In addition to engine, transmission, and suspension configurations, options make this truck as customizable as any light truck on the market.
