Looks like a 2011 Yukon XL, correct? Nothing too crazy about it. Wheel replacement - 10/31/2013 & 30,461 miles, Battery replacement - 9/05/2014 & 37,004 miles, Temperature valve actuator replacement - 9/09/2014 & 37,011 miles. If you can get a CarFax report on it, and it is clear, you are likely alright.
