Unexpected opportunity to buy a 2012 Yukon XL Dinali, 140,000 miles. Worried that the mileage is high but the price seems decent at 12,500. Exterior is immaculate except for a little rust about the size of a nickel inside the door rocker panel. Has recently had new brakes and left suspension leaving sensor replace, front stabilizer link replaced, rear drive shaft assembly replaced. I am hoping to know if I am in for known issues that will pop up. I ADORE the truck but need reliable and my money pit is empty. ThNk you in advance for any help!
