To estimate the price of the 2013 GMC Yukon Denali V8 6.2L with 319000 km mileage, I first looked at the selling prices of similar cars. The closest matches are: a 2013 GMC Yukon Denali V8 6.2L with 255000 km sold for 25000 SAR on 2024-04-29, and another 2013 GMC Yukon Denali V8 6.2L with 213000 km sold for 37000 SAR on 2024-05-10. Given the higher mileage of the target car, its value should be lower. Next, I considered listed prices: a 2013 GMC Yukon Denali V8 6.2L with 287000 km was listed for 56500 SAR but delisted on 2024-03-26, and another with 255000 km was listed for 36000 SAR but delisted on 2024-04-30. These listings suggest a higher asking price than actual selling prices. Considering the depreciation and higher mileage, I estimate the market price to be lower than the lowest selling price but higher than the lowest listed price.
