2006 GMC Sierra 1500 FAQ

Can you elaborate on the "Performance Edition Package" and the "Towing/Camping Package"? 

While the Performance Edition Package is listed as available for the 4WD pickup, it is actually only available on the regular RWD pickup. That is a mistake in our listings. However, that package contains the 6.0 V8, a lowered sport suspension, a heavy duty transmission, and 20” wheels among other things.   


Our value for a “Towing/Camper Package” is for any equipment that assists in the towing of a trailer, etc. by a vehicle. This equipment usually, but doesn’t always, include a trailer hitch, a wiring harness, auxiliary oil and transmission coolers among other things. NADA’s values are designed and intended to assist users in performing their own valuation of a particular used vehicle. The process by which users of NADA determine valuation is inherently subjective. Individual vehicles may have an actual value that is higher or lower than the estimated values created by NADA.
