I started by examining the selling prices of similar 2016 Mazda CX-9 V6 3.7L High+ Premium (Top) models. A car with 199900 km sold for 48000 SAR on 2023-10-28, and another with 247500 km sold for 39000 SAR on 2023-11-09. The target car has higher mileage at 294580 km, which suggests a lower price. I also considered a 2015 model with 283000 km that sold for 41000 SAR on 2024-01-17, indicating a depreciation trend. The listed prices for similar cars with high mileage range from 38500 to 45000 SAR, but these are typically higher than actual selling prices. Considering the target car's high mileage and average condition, I estimate its market price to be slightly lower than the 39000 SAR sale, around 37000 SAR.
