 My husband and I just purchased a 2005 Kia Sportage, pre-owned, with 135k miles, due to our limited budget. The Carfax didn't list any maintenance, and the test-drive and subsequent independent pre-purchase inspection confirmed that there were problems. The timing belt system had not been replaced at 100k miles, the battery was original (and died right after purchase), and the A/C was non-functional. We were able to knock off a lot from the price due to all the work that needed to be done (most of it simply maintenance that was put off, not true issues). A/C problem due to climate control module and is being replaced. Hoping we don't regret this purchase.
