To estimate the price of the 2019 Chevrolet Spark I4 1.4L LT (Base) with 221000 km mileage, I first looked at the selling prices of similar cars. A 2019 model with 120500 km sold for 26000 SAR in November 2023, and a 2020 model with 34000 km sold for 31500 SAR in February 2024. Another 2020 model with 94000 km sold for 26250 SAR in September 2023, and a 2020 model with 72000 km sold for 22000 SAR in July 2024. Given the higher mileage of the target car, its value would be lower. I also considered listed prices: a 2019 model with 221000 km was listed for 22000 SAR, and similar models with slightly lower mileage were listed between 23000 and 24000 SAR. Considering the higher mileage and the condition of the car, I adjusted the price downwards from the listed prices.
