To estimate the price of the 2019 GMC Yukon SLE V8 5.3L XL SLE, I focused on the selling prices of similar cars. The most relevant data point is the 2019 GMC Yukon V8 5.3L SLE with 175,000 km sold for 106,000 SAR in March 2024. This car is the same variant and only slightly older than the target car. The 2018 GMC Yukon SLT V8 5.3L with 205,700 km sold for 120,000 SAR in October 2023, but it is a higher trim and has more mileage. The 2017 GMC Yukon SLE V8 5.3L with 177,000 km sold for 86,000 SAR in July 2024, which is older and has more mileage. Considering the target car's lower mileage of 108,178 km and its good condition, I estimate its price slightly higher than the 2019 SLE sold for 106,000 SAR, accounting for the lower mileage and current market conditions.
