To estimate the price of the 2014 Mazda CX-9 V6 3.7L High+ Premium (Top) with 136,000 km mileage, I focused on the selling prices of similar cars. The most relevant data points are: a 2014 model with 113,677 km sold for 58,000 SAR in February 2024, and another 2014 model with 145,000 km sold for 50,000 SAR in August 2023. A 2014 model with 196,000 km sold for 35,500 SAR in January 2024, and a 2014 model with 256,000 km sold for 35,000 SAR in April 2024. Considering the target car's mileage and condition, I estimate its price to be slightly lower than the 58,000 SAR sale due to higher mileage but higher than the 35,000-35,500 SAR sales due to lower mileage and similar condition. Thus, I estimate the market price to be around 48,000 SAR.
