To estimate the price of the 2015 GMC Yukon V8 5.3L SLE (Base) with 162000 km mileage, I primarily considered the actual selling prices of similar cars. The most relevant data point is a 2015 GMC Yukon V8 5.3L SLE (Base) with 161000 km sold for 82000 SAR on 2023-12-16. Another close match is a 2017 model with 177000 km sold for 86000 SAR on 2024-07-23. The 2016 model with higher mileage (269000 km) sold for 60000 SAR on 2024-02-15. Considering the mileage and year differences, the 2015 model with similar mileage sold for 82000 SAR is the most relevant. The listed price of a similar car was 83000 SAR but was delisted, indicating it might not have sold at that price. Therefore, the estimated market price is slightly adjusted based on these data points.
