Considering these factors, you'll likely find 2007 Chevrolet Avalanches listed anywhere from a few thousand dollars for those in rough condition and high mileage, to $15,000 or more for exceptionally well-maintained examples with low mileage. It's best to check online used car listings (like Autotrader, Cars.com, Kelley Blue Book, etc.) in your specific area to get a more accurate price range.
