new wife and i traded her 2003 kia sorento in last year since it was only a 5 passenger. found a 2003 fully loaded envoy xl with everything on it and 4x4 with 100,000 miles. found original sticker in glove box. thing listed for 40,000 brand new. with trade in we paid 5400 for it in april 2012. now it has 113,000 miles. things i have done since getting it are
1. added some freon
2. replaced rear air bags and shocks
3. replaced spark plugs
4. cleaned throttle body
in next month i need to change clanking front sway bar end links and change original front shocks, and change tranny fluid, rear diff, front diff and transfer case oil.
other than that, no problems with it, runs like a top. averages around 19.5 to 20 mpg on the higway and about 14 in the city.
