To estimate the price of the 2018 Chevrolet Traverse V6 3.6L LT (AWD) (Mid) with 66500 km mileage, I considered the following data points: 1) A 2017 model with 146000 km sold for 43000 SAR in average condition. 2) A 2019 model with 73000 km sold for 72000 SAR in average condition. 3) A 2016 model with 176500 km sold for 35000 SAR in good condition. 4) Another 2019 model with 127500 km sold for 65000 SAR in average condition. 5) A 2020 model with 58000 km sold for 89000 SAR in average condition. Given the target car's lower mileage and good condition, I adjusted the price upwards from the 2017 and 2016 models but below the 2019 and 2020 models due to the year difference.
