To estimate the price of the 2015 Mazda CX-9 V6 3.7L LTD AWD (Top) with 231140 km mileage, I considered several data points. First, I looked at the selling prices of similar cars: a 2017 Mazda CX-9 2.5L I4 TC AWD with 79990 km sold for AED 70000 and another 2017 Mazda CX-9 I4 2.5L Turbo with 125000 km sold for AED 60000. These cars are newer and have lower mileage, so their higher prices are expected. Next, I considered the offer accepted for a 2015 Mazda CX-9 3.7L V6 AWD GT AWD (Mid) with 213400 km at AED 39000. This car is similar in age and mileage but a lower trim. For listed prices, a 2015 Mazda CX-9 V6 3.7L LTD AWD (Top) with 231234 km was listed for AED 39500, and a 2015 Mazda CX-9 3.7L V6 LTD AWD (Top) with 177100 km was listed for AED 46500. Considering the higher mileage and average condition of the target car, I adjusted the price downwards from these listings. Factoring in all these data points, I arrived at a reasonable market price estimate.
