I started by looking at the selling prices of similar cars. The first car, a 2020 Mazda CX-9 I4 2.5L Turbo Charged with 161000 km and in average condition, sold for 74000 SAR on 2024-01-05. The second car, a 2020 Mazda CX-9 I4 2.5L with 146000 km and in average condition, sold for 89000 SAR on 2024-04-30. Given that the car to be estimated is in good condition and has a similar mileage of 157000 km, it should be valued higher than the first car but comparable to the second car. Next, I reviewed the listed prices of similar cars. The prices ranged from 86000 SAR to 115000 SAR, with the most relevant being the 2020 Mazda CX-9 I4 2.5L Turbocharged, High+ Premium (Top) variant with 157000 km listed for 103500 SAR. Considering the actual selling prices and the listed prices, I estimated the market price of the car.
