To estimate the price of the 2019 Mazda CX-9 I4 2.5L Grade 1 (Base+), I focused on the selling prices of similar cars. The most relevant data point is the 2018 Mazda CX-9 I4 2.5L Turbocharged with 160,000 km, sold for 57,500 SAR on 2024-09-15, as it shares the same engine size and variant (Base+). Another relevant data point is the 2019 Mazda CX-9 I4 2.5L with 88,000 km, sold for 77,000 SAR on 2024-07-06, but it is a higher variant (Mid+). Considering the higher mileage of 203,500 km for the car in question, I adjusted the price downwards. The 2019 model with 120,000 km sold for 67,000 SAR on 2023-08-18, which also supports a lower estimate due to the higher mileage of the car in question. Based on these comparisons, I estimated the market price by considering the depreciation due to mileage and the lower trim level.
