To estimate the price of the 2018 Chevrolet Trailblazer V6 3.6L Standard with 146200 km mileage, I considered the following data points: The new 2025 Chevrolet Trailblazer Standard SUV is priced at SAR 121500. Assuming a 10% annual depreciation, the 2018 model would have depreciated for 7 years, resulting in a depreciation factor of approximately 52%. This gives an estimated value of around SAR 58320. Additionally, I looked at listed prices of similar cars: a 2016 model with 136400 km is listed for SAR 45000, and a 2019 model with 82000 km is listed for SAR 65500. Considering the 2018 model's mileage and condition, I adjusted the price to be between these two listings, closer to the lower end due to higher mileage and average condition.
