2008 Hummer H2 Reviews

Purchased in Jan.2010 to be used as everyday driver and 25' boat hauler. Have not regretted trading in a perfectly good 2007 Acura MDX for it. I have added the nominal performance upgrades (exhaust, intake, chip) which certainly boosted power but no increase over stock mpg. 13mpg at best on highway. The 2008 + up model is the way to go for this brand - many improvements over 2007 and earlier. This is one kickass ride!
