I analyzed the selling prices of similar cars, focusing on those with the same variant and condition as the car in question. The most relevant data point is the 2023 Changan CS35 I4 1.4L Turbocharged Plus GDI Limited (Top) with 17000 km mileage, sold for 59000 SAR on 2024-01-08. Another similar car with 18000 km mileage sold for 64000 SAR on 2024-05-27. Considering the car in question has 16000 km mileage and is in good condition, I estimate its price to be slightly lower than 64000 SAR but higher than 59000 SAR, given the market trend and condition.
