First, I considered the selling price of the 2020 GAC GA8 I4 2.0L Turbocharged Standard variant with 89000 km mileage, which sold for SAR 49300 on 2023-09-15. Given that the car to be estimated is a 2021 model with lower mileage (28500 km) and a higher trim (Flagship), it should be valued higher. Next, I looked at the offer accepted for a 2020 GAC GA8 I4 2.0L Turbocharged Luxury variant with 116000 km mileage at SAR 53000 on 2024-09-23. Since the car to be estimated is a higher trim (Flagship) and has significantly lower mileage, it should be valued higher than this offer. Finally, I noted the listed price of a similar 2020 GAC GA8 I4 2.0L Turbocharged Luxury variant with 116000 km mileage at SAR 58000. Considering the car to be estimated is a 2021 model with much lower mileage and a higher trim, the estimated price should be higher than this listed price.
