To estimate the price of the 2021 Mazda CX-9 2.5L GT Standard with 77567 km mileage, I considered several data points. First, I looked at the selling prices of similar cars: a 2020 Mazda CX-9 Standard with 90000 km sold for 98500 AED and another for 92500 AED, both in good condition. A 2019 Mazda CX-9 GT AWD with 75000 km sold for 89000 AED, and a 2020 Mazda CX-9 LTD AWD with 104365 km sold for 93000 AED. These prices suggest a range of 89000-98500 AED for similar models. Next, I considered dealer-sold prices: a 2021 Mazda CX-9 GT with 64839 km sold for 103695.75 AED and a 2021 Mazda CX-9 LTD with 90252 km sold for 89241.5 AED. These prices indicate a range of 89241.5-103695.75 AED. Finally, I reviewed listed prices: a 2021 Mazda CX-9 GT Standard with 77567 km listed for 119990 AED and a 2021 Mazda CX-9 LTD with 90252 km listed for 104990 AED. Considering the car's condition is not specified as good, I adjusted the estimate slightly lower than the dealer-sold GT price.
