I started by looking at the selling prices of similar cars. The closest match is the 2022 Changan Alsvin I4 1.5L Advanced (Top) with average condition and mileage ranging from 44,000 km to 110,400 km, selling between 19,000 SAR and 27,500 SAR. The 2020 Changan Alsvin I4 1.5L Standard (Base) with higher mileage (77,500 km and 79,000 km) sold for 20,000 SAR and 19,000 SAR respectively. Given that the car in question is a 2020 model with 38,000 km, it has lower mileage than most comparables. The 2022 models with similar mileage and condition sold for around 25,500 SAR to 27,500 SAR. Considering the depreciation and the fact that the car in question is a 2020 model, I adjusted the price slightly lower than the 2022 models but higher than the 2020 Standard (Base) models.
