my Hummer H3 true story.
Factory warranty ends at 80,000 my truck was at 80,413 over limit.
I bought my 2006 H3 Adventure pakage when it hit the market. For all of its faults, i dont consider anything else. Airaid filters make a big difference in power and milage. it is a fun ride, up high, safe, go anywhere.
Just bought this H3. Bought it for its weight (far better than the Colorado it is built on)and the full time 4WD. For the lead foots in your household--I have two, it keeps the car on the road, the tires off the curbs, and the back end from swerving into the opposing land. Still need more clearance for off roading. BUT IS IS CALLED A TACTICAL EDITION. WHAT DOES THAT MEAN? NO TOP LIGHTS, AND BACKED OUT WHEELS IS ALL I SEE, NO CHROME. ANY HELP?
We bought this H2 new in the fall of 2005. It now has over 105,000 miles on it and continues to perform extremely well. The only problems we have had is that we've gone through a couple batteries and a minor suspension problem in the rear. This is a great vehicle that has been used for a variety of "hauling" applications and it continues to perform beautifully. The only down side is that the vehicle only gets 11 mpg (whether towing a load or not) and I would not recommend it to a driver 6' tall or greater that wants to be able to stretch their legs out (the seats just don't go back that far).
Great vehicle. Wouldn't drive anything smaller. Better gas millage than Dodge Dakota. Stands out in a crowd!
