The Chevrolet Avalanche Z66 package was a variant of the Avalanche pickup truck produced from 2001 to 2013. However, specific production numbers for the Z66 trim alone are not widely reported, as manufacturers typically release overall production figures rather than breakdowns by specific trim levels. The Avalanche itself saw total production of around 580,000 units during its run. For precise numbers on the Z66 variant, more detailed manufacturer records would be needed.

The blue book value of a Chevrolet Avalanche Z66 with 170,000 miles can vary based on its condition, location, and specific features. Typically, prices for vehicles at this mileage range can fall between $5,000 and $10,000. To get an accurate estimate, it's best to check resources like the Kelley Blue Book or NADA Guides, which provide current market values based on detailed criteria.
