To estimate the price of the 2023 Changan UNI-V I4 1.5L Limited (Top) with 75000 km mileage, I considered the listed prices of similar cars. The 2024 model with 25000 km is listed at SAR 60000, and two 2023 models with much lower mileage (19700 km and 18000 km) are listed at SAR 67500 each. Given the higher mileage of the car in question (75000 km), I expect a significant depreciation from these listed prices. The 2024 model's lower price suggests a depreciation trend. Considering the mileage and average condition, I estimate the market price to be lower than the lowest listed price, accounting for the additional mileage and condition.
