I'll start out with my 07 H3X with 75k, my 08 H3 Alpha 9k , I guess you can figure out which one gets the best MPG! LOL, Lady out the street has 158k on her 06 H3

 

07 adventure, just turned 42,600 miles
I guess I might be in the middle

Oh, and no problems at all, I really like that part and a great dealer

 

2006 Hummer H3 Lux with just 28k original miles!!!! I think i beat everyone!

 

Other than my mirror and a dead battery i've not had any problems yet either

 

I have 24,000 miles on my 2006 h3. Bought it with 6,000 two years ago. I got really lucky I drove by the dealership right after the previous owner have it back after lease. Walked in and bought it 2hrs after the pervious owner dropped it off.

 

My 06 lux has (sorry i am Canadian so in kilometers) 168873 km
unlike the rest i have lots of troubles. But have only had it six months. I think it was not maintained enough with the previous owner.

 

I have 41k on my 08 H3 Alpha. I also like the sound of no problems at all

 

My 06 H3 Adventure with 52K ( around 84K Kilometers)
No problems on the way

 

50,250 miles on my 2007 adventure i5.

 

My '06 Yellow Lux. has 29K..Just bought a '79 Mercedes 450SL..that is almost EXACTLY the same color..and has Tan leather like the H3..
