The car to be estimated is a 2022 Changan Alsvin I3 1.4L Advanced with 100,000 km mileage. The closest comparable cars are the 2022 Changan Alsvin I4 1.5L Advanced (Top) variants. The selling prices for these range from 19,000 SAR to 26,000 SAR. The most relevant data points are: a car with 105,000 km sold for 26,000 SAR, a car with 84,000 km sold for 25,500 SAR, a car with 90,000 km sold for 26,000 SAR, and a car with 110,400 km sold for 25,500 SAR. Given the target car's mileage and condition, I estimate its price to be slightly lower than the average of these due to its higher mileage and smaller engine size. The average of the closest matches is approximately 25,000 SAR, so I adjust slightly downward to account for these factors.
