First, I considered the selling price of the 2021 Mazda 6 I4 2.5L Turbocharged, which sold for 90500 SAR in October 2023. This car is a higher variant (Ignite) and in good condition, whereas the target car is a 2023 model, mid variant (R), and in average condition. The new price difference between the Ignite and R variants is significant, with the Ignite priced at 126500 SAR and the R at 127075 SAR. Given the target car's average condition and higher mileage, I adjusted the price downwards. Next, I looked at the listed prices of similar 2023 Mazda 6 I4 2.5L R (Mid) variants. One was listed for 75000 SAR with the same mileage, and another for 76500 SAR with lower mileage. Considering these factors, I estimated the market price accordingly.
