To estimate the price of the 2017 GMC Yukon SLE V8 5.3L with 187341 km mileage, I first considered the selling price of a similar 2017 GMC Yukon SLE V8 5.3L with 177000 km mileage, which sold for 86000 SAR in July 2024. This car is very similar in terms of year, variant, and condition. I also looked at a 2016 model with higher mileage (269000 km) that sold for 60000 SAR in February 2024, and a 2016 model with 207000 km that sold for 80000 SAR in September 2024. These prices suggest a depreciation trend. Additionally, a 2018 SLT variant with 192000 km sold for 100000 SAR in March 2024, indicating a higher price for a higher trim. The listed prices for similar 2017 SLE models were 85500 SAR and 88500 SAR, but these are typically higher than actual selling prices. Considering the selling price of the most similar car (86000 SAR) and adjusting slightly for the higher mileage of the target car, I estimate the market price to be slightly lower.
