Hey guys, been visiting here for a while but first time posting. Anyway, I am considering buying this 2008 Tahoe but the carfax is giving me second thoughts. It seems to have had a lot of things replaced/worked on such as pinion seal replaced, transfer module/computer reprogrammed, engine/powertrain computer/module replaced, window regulator replaced, lumbar system replaced, etc. I could be over analyzing it but I don't want to buy a lemon. The Tahoe is certified with 39k miles, but I am still concerned. I appreciate any feedback.
