Bought the Yukon new in Dec. 2001. Drove it for business (mostly highway) to around 180,000 in 2008. Since then my sons have taken the truck to college with them. Now has approx. 215,000. I have always changed the oil between 3-5000 miles. We have only had to do routine maintenance (brakes, belts, tires etc.) The only irritating issue has been the drivers side window motor. Have had to replace this 3 times. Otherwise very, very solid truck. In fact, bought a 2009 Yukon and love it. The key to any car is to keep up with routine maintenance and don't beat it to death. Take care of your car.
