To estimate the price of the 2021 Mazda CX-9 I4 2.5L Turbo Charged Grade 1 Premium (Mid+), I first considered the selling prices of similar cars. The most relevant data point is a 2021 Mazda CX-9 with a similar variant (High+ Premium) sold for 132800 SAR in May 2023 with lower mileage (48000 km). Another relevant sale is a 2019 model with the same variant as the target car, sold for 77000 SAR in July 2024 with similar mileage (88000 km). The 2021 model with a higher variant (High+) and higher mileage (119500 km) sold for 109000 SAR in November 2023. The listed price for a similar 2021 model with lower mileage (63000 km) was 128000 SAR, but it was delisted, indicating it might not have sold at that price. Considering the target car's mileage (71200 km) and condition, I estimate its market price by adjusting the 2021 High+ Premium sale price downwards due to the lower variant and higher mileage, while also considering the 2019 sale as a lower bound.
