To estimate the price of the 2017 Mazda 6 I4 2.5L Core (Base+), I considered several data points. First, I looked at the selling prices of similar cars. A 2017 Mazda 6 with 155000 km in good condition sold for 46000 SAR, while another 2017 model with 207000 km in average condition sold for 29500 SAR. A 2016 model with 204000 km in average condition sold for 37000 SAR, and another 2016 model with 175000 km in average condition sold for 37500 SAR. Given the target car's mileage of 174000 km and average condition, it is reasonable to place its value between these figures. Additionally, the listed prices for similar cars ranged from 40000 to 48500 SAR, but these are typically higher than actual selling prices. Considering the car's condition, mileage, and the most relevant selling prices, I estimated the market price accordingly.
