To estimate the price of the 2013 Mazda CX-9 3.7L V6 AWD Signature Edition (Top++), I first considered the selling price of a similar 2011 Mazda CX-9 3.7L V6 LTD AWD (Top) with 182000 km mileage, which sold for AED 23000 on 2024-02-02. This car is older and has higher mileage, so the target car should be valued higher. Next, I looked at an offer accepted for a 2013 Mazda CX-9 3.7L V6 LTD AWD (Top) with 125200 km mileage at AED 28000 on 2023-10-14. This car has lower mileage but is of the same year, suggesting a similar or slightly higher value for the target car. For listed prices, a 2013 Mazda CX-9 3.7L V6 AWD Signature Edition (Top++) with the same mileage is listed for AED 31500, but listed prices are generally higher than selling prices. Considering these data points, I adjusted for the higher trim and similar mileage, leading to a final estimate.
