To estimate the price of the 2021 GMC Yukon SLE V8 5.3L, I first considered the selling prices of similar cars. The most relevant data point is the 2021 GMC Yukon SLE V8 5.3L with 21000 km sold for 183000 SAR in April 2024. Given the target car's higher mileage of 117000 km, I expect a lower price. The 2019 GMC Yukon SLE V8 5.3L with 175000 km sold for 106000 SAR in March 2024, indicating a significant depreciation with higher mileage. The listed price of a similar 2021 model with 96000 km was 170000 SAR, but it was delisted, suggesting it might not have sold at that price. Considering these factors, I estimate the market price by adjusting the 183000 SAR for the higher mileage, resulting in a lower value.
