GM executives are quick to point out that their large SUVs, including the Chevrolet Tahoe, have ranked number one in initial quality tests over the past several years, which coincides with the manufacturer’s dominant 62-percent share of this market. Large SUV sales once amounted to one million units, but rising gas prices are expected to push that number down to 700-800,000 trucks annually. Despite this downsizing, GM is intent on using its redesigned SUVs, including the 2007 Chevrolet Tahoe, to maintain its current number of sales by capturing more of the large SUV market.
