To estimate the price of the 2015 Mazda CX-9 V6 3.7L High+ Premium with 140130 km mileage, I first considered the most recent selling price of a similar car with 145600 km mileage and average condition, which sold for 41500 SAR on 2024-09-12. This is the closest match in terms of condition and mileage. Other selling prices for similar cars with better condition and lower mileage ranged from 40000 SAR to 66500 SAR, but these were sold earlier in 2023, and the condition was better. The listed prices for similar cars with similar mileage and condition range from 35000 SAR to 60000 SAR, with the most recent listing at 45000 SAR not yet delisted. Considering the average condition and the mileage of the car in question, the most relevant data point is the recent sale at 41500 SAR, which aligns with the lower end of the current market listings.
