To estimate the price of the 2015 GMC Yukon V8 5.3L SLE (Base) with 179000 km mileage in good condition, I considered the following data points: 1) A similar 2015 GMC Yukon V8 5.3L SLE (Base) with 161000 km mileage in average condition sold for 82000 SAR on 2023-12-16. 2) A 2016 GMC Yukon V8 5.3L SLE (Base) with 269000 km mileage in average condition sold for 60000 SAR on 2024-02-15. 3) A 2017 GMC Yukon V8 5.3L SLE (Base) with 177000 km mileage in average condition sold for 86000 SAR on 2024-07-23. 4) A 2014 GMC Yukon V8 5.3L XL SLE (Base+) with 179000 km mileage in good condition sold for 49000 SAR on 2023-09-07. 5) Listed prices for similar 2015 GMC Yukon V8 5.3L SLE (Base) with 161000-162000 km mileage were 83000-85000 SAR. Considering the car's good condition and mileage, I adjusted the price slightly higher than the 2015 model with average condition and lower mileage, but lower than the 2017 model with similar mileage.
