The sale of SUVs has slightly abated recently due to rising prices of fuel but GMC seems not daunted by this phenomenon. Just last October 5, 2005, GMC unveiled the 2007 Yukon and the flagship Yukon Denali full-size SUV at the California International Auto Show in Anaheim. In GMCs words, these new Yukon editions are the most powerful, agile, fuel efficient and refined among GMCs sport utilities. Inside and out the new GMC Yukon and Yukon Denali models offer the best that you can ask for from a full-size truck.
