To estimate the price of the 2013 Chevrolet Spark LS I4 1.2L LT (Base) in bad condition with 201000 km mileage, I started with the new car price of the 2025 Chevrolet Spark LT (Base) Hatchback, which is SAR 49500. Given that cars depreciate by approximately 10% per year, the 2013 model would have depreciated for 12 years. Using the formula for depreciation, the value of the car would be 49500 * (0.9^12) = approximately SAR 14200. Considering the car is in bad condition and has high mileage, I further reduced the estimated price by around 30% to account for these factors, resulting in an estimated price of approximately SAR 9940.
