To estimate the price of the 2023 Changan CS35 TURBO I4 1.4L Plus GDI Limited (Top) with 40000 km mileage, I first considered the selling prices of similar cars. A similar car with the same variant and good condition sold for 64000 SAR on 27 May 2024, but it had lower mileage (18000 km). Another car with a lower variant (Plus GDI Trend) and higher mileage (50772 km) sold for 47500 SAR on 3 Oct 2024. A mid-variant (Plus GDI Smart) with low mileage (6476 km) sold for 53000 SAR on 29 Jul 2024. The target car has average condition and higher mileage than the 64000 SAR car, suggesting a lower price. I also reviewed listed prices: a similar variant with 36000 km was listed for 48500 SAR, and another with 33000 km was listed for 55000 SAR. Considering these data points, the estimated market price is adjusted for the higher mileage and average condition.
