I started by examining the selling prices of similar cars. The most relevant data point is the 2015 Mazda CX-9 V6 3.7L High+ Premium (Top) with 145600 km sold for 41500 SAR in September 2024. This car is very similar in variant and condition to the target car, but with slightly lower mileage. Another relevant data point is a similar car with 121000 km sold for 62000 SAR in June 2023, but it was in good condition, which likely increased its value. The car with 212000 km sold for 45500 SAR in March 2024, but it was a High+ (Mid) variant, which is less valuable than the High+ Premium (Top). Considering the target car's mileage of 165000 km and average condition, its value should be slightly higher than the 41500 SAR car due to lower mileage but lower than the 62000 SAR car due to condition. I also considered listed prices, where similar cars with mileage around 165000 km were listed between 45000 SAR and 60000 SAR, but these are typically higher than actual selling prices. Therefore, I estimate the market price to be slightly above the 41500 SAR selling price, considering the mileage and condition.
