To estimate the price of the 2019 Mazda CX-3 I4 2.0L GT 2WD (Mid) with 140800 km mileage, I first looked at the selling price of a similar car with 158500 km mileage, which sold for AED 38000 on 2023-11-07. Given the similar condition and specs, this is a strong reference point. Next, I considered the listed prices of similar cars. The closest match is a car with the same variant and mileage listed for AED 46500, but listed prices are generally higher than selling prices. Other listed prices for similar variants range from AED 33000 to AED 60300, with higher prices for lower mileage and better conditions. Considering the car's good condition and the average depreciation, I adjusted the selling price reference slightly upwards. The final estimate balances the actual selling price and the listed prices, accounting for the car's condition and mileage.
