To estimate the price of the 2018 Mazda CX-3 GT 2WD (Mid) with 144,500 km mileage, I first considered the selling prices of similar cars. A 2019 CX-3 GT 2WD (Mid) with 158,500 km sold for AED 38,000 on 7 Nov 2023. This car is a year newer but has higher mileage, suggesting a slightly lower value for the 2018 model. An offer of AED 40,500 was accepted for a 2018 GT 2WD (Mid) with 155,500 km on 3 Dec 2023, and another offer of AED 37,000 for a similar car with 168,200 km on 12 Dec 2023. These offers indicate a price range around AED 37,000 to AED 40,500. Considering the car's condition and mileage, I estimate the market price to be slightly below the higher offer. Listed prices for similar 2019 models are around AED 46,500, but these are typically higher than actual selling prices. Therefore, I estimate the market price for the 2018 model to be around AED 39,000.
