To estimate the price of the 2019 Mercedes GLS450 V6 3.0L Top with 37000 km mileage, I first considered the selling price of a similar 2020 model with 65000 km sold for SAR 335000 in February 2024. Given the 2020 model's higher mileage, the 2019 model with lower mileage should be valued higher. Next, I looked at the listed prices of similar cars. The closest match is a 2019 GLS450 with the same mileage listed for SAR 419500, but listed prices are generally higher than selling prices. Other listed prices for 2020 models range from SAR 330000 to SAR 383500, with higher mileage. Considering the depreciation and the lower mileage of the 2019 model, I adjusted the price down from the highest listed price but above the selling price of the higher mileage 2020 model.
