To estimate the price of the 2015 GMC Yukon XL Denali V8 6.2L, I focused on the selling prices of similar cars. The closest match in terms of variant and engine size is the 2013 GMC Yukon V8 6.2L Denali, which sold for 37000 SAR and 25000 SAR, but these had much higher mileage and were older. The 2015 GMC Yukon V8 5.3L SLE sold for 82000 SAR, but it is a base variant with higher mileage. The 2014 GMC Yukon XL SLE with good condition and lower mileage sold for 58300 SAR. Considering the Denali is a top variant and the car in question has lower mileage and is in good condition, I adjusted the price upwards from the 2014 XL SLE. The 2016 models with higher mileage sold for 60000 to 80000 SAR, indicating a higher value for newer models. Taking into account the premium for the Denali trim and the lower mileage, I estimated the price to be higher than the 2014 XL SLE and closer to the higher end of the 2016 models.
