To estimate the price of the 2018 GMC Yukon V8 5.3L XL SLE (Base+), I first considered the selling prices of similar cars. A 2018 Yukon SLT (Mid) with 192,000 km sold for 100,000 SAR in March 2024, and a 2017 Yukon SLE (Base) with 177,000 km sold for 86,000 SAR in July 2024. The target car is a 2018 SLE (Base+) with higher mileage (250,000 km) and average condition, suggesting a lower price than the SLT and possibly similar to the 2017 SLE. The 2016 SLE (Base) with 269,000 km sold for 60,000 SAR in February 2024, indicating a depreciation trend. The listed price for a similar 2018 XL SLE with 274,000 km is 91,000 SAR, but listed prices are often higher than selling prices. Considering these factors, I estimate the market price to be slightly lower than the listed price, around 85,000 SAR.
