The car to be estimated is a 2023 Mazda 6 2.0L S Grade (Base) with 51528 km mileage. The closest data point is an offer accepted for a 2023 Mazda 6 2.0L S Grade (Base) with 18258 km mileage at AED 81000 on 2024-08-06. Given the higher mileage of the car to be estimated, we should adjust the price downwards. The selling prices for the 2.5L V Grade (Mid) variant range from AED 71000 to AED 75000, which are higher trims. Considering the base variant and higher mileage, a reasonable estimate would be lower than the accepted offer for the base variant. Therefore, I estimate the market price to be around AED 68000.
