My wife bought her '02 Explorer XTS used ten years ago for $3500, with 100K on the odometer, and now it's got 156K on the odometer. It was probably part of an estate sale to the dealer. Everything works, including the 4WD and the cruise control. The a/c was fixed about five years ago. The original stereo was a factory piece of crap, which we replaced immediately with a new deck with a USB port. The "Check Engine" light has been on the whole time. Our regular mechanic told us the code was for an O2 sniffer, and he could get the light to go out, but because of the age of the engine, it would be coming on again shortly. He also said if the light began flashing, we should be concerned. On long trips, it gets 20-21 MPG, and around town it gets 12-15 MPG. Lately, we've measuring fuel consumption in terms of weeks since the last re-fueling. If we have not done any road trips, re-fueling when she gets her SS check is good. My car, a 2000 Taurus SES, took the big sxxt with a blown head gasket at 255K in late September last year. We decided to not replace it.
