We hunted for weeks for a bright yellow Xterra to replace the one we just lost to some black ice. Ultimately we found one that had very high miles -- more than 180k. Normally we would have steered clear, but the Carfax showed amazingly detailed information for all 180k miles of this 2005 model. It included nearly every oil change from dealers (as well as maintenance done by a local "quick lube" chain store). Not only did it show oil changes, but things like exterior light checks, fluid flushes and a bunch of other things. It was a lot more detail than I was expecting, and that Carfax detail gave us the extra push to go ahead and buy this high mileage car with the confidence that it was genuinely cared for.
