I started by looking at the selling prices of similar cars. The most relevant data point is the 2022 Mazda CX-9 I4 2.5L High+ Premium (Top) with 52000 km sold for 103000 SAR on 2024-05-27. Given that the car in question has higher mileage (91500 km), I adjusted the price downwards. Another relevant data point is the 2022 Mazda CX-9 I4 2.5L Turbo Charged with 15000 km sold for 140000 SAR on 2024-01-08, but this car has significantly lower mileage. The 2020 Mazda CX-9 I4 2.5L with 93000 km sold for 110000 SAR on 2024-04-23, which is closer in mileage but older. Considering these factors, I estimated the price by giving more weight to the 2022 model with 52000 km and adjusting for the higher mileage and current market conditions.
