To estimate the price of the 2019 Chevrolet Impala V6 3.6L LT (Mid) with 208500 km mileage and average condition, I considered the following data points: 1. A similar 2019 Impala LT (Mid) with 198000 km and good condition sold for SAR 53000 on 2024-09-03. Given the better condition and slightly lower mileage, I adjusted the price downwards for the average condition and higher mileage of the target car. 2. A 2018 Impala LT (Base) with 360000 km sold for SAR 36500 on 2023-10-23. This car has a higher mileage and is a base variant, so the target car should be valued higher. 3. A 2019 Impala LTZ (Top) with 22000 km sold for SAR 90000 on 2024-03-13. This car is a higher trim and has much lower mileage, so the target car should be valued significantly lower. 4. A 2018 Impala LS (Base) with 166000 km and average condition sold for SAR 30000 on 2024-07-23. This car has lower mileage but is a base variant, so the target car should be valued higher. 5. Listed prices for similar cars range from SAR 30000 to SAR 90500, with a 2019 Impala LT (Mid) with 198000 km listed for SAR 53000. Considering these factors, I estimated the market price for the target car.
