To estimate the price of the 2018 GMC Yukon V8 5.3L SLT (Mid) with 132000 km mileage, I considered several data points. First, a similar 2018 GMC Yukon SLT with 205700 km sold for 120000 SAR on 2023-10-12. Given the lower mileage of the target car, it should be valued higher. Another 2018 GMC Yukon SLT with 192000 km sold for 100000 SAR on 2024-03-15, but it was in average condition, so the target car should be valued higher due to its good condition. A 2019 GMC Yukon Denali with 74000 km sold for 170000 SAR on 2023-12-31, but this is a higher trim. A 2019 GMC Yukon SLE with 175000 km sold for 106000 SAR on 2024-03-07, which is a lower trim. The listed prices for similar cars are 119000 SAR and 140000 SAR, but these are generally higher than actual selling prices. Considering these factors, the estimated market price is derived by adjusting for mileage, condition, and trim differences.
