To estimate the price of the 2020 Mazda CX-9 2.4L Turbocharged Signature Edition with 71000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars: a 2020 Mazda CX-9 2.5 i4 with 90000 km sold for 98500 AED and 92500 AED, and a 2020 Mazda CX-9 2.5L I4 4WD TC with 104365 km sold for 93000 AED. These cars have higher mileage and lower trims. Next, I considered the offer accepted for a 2020 Mazda CX-9 2.5L Signature Edition with 35000 km at 120500 AED, which is a higher trim but with much lower mileage. Dealer sales of similar cars ranged from 90690.75 AED to 101991.5 AED, with the closest match being a 2020 Mazda CX-9 2.5L SIGNATURE with 81072 km sold for 101991.5 AED. Given the target car's mileage and trim, I adjusted the price slightly lower than the highest dealer sale but higher than the average selling prices of lower trims.
