The car in question is a 2018 Mercedes SLC200 I4 2.0L Twin Turbo Standard Convertible with 65,000 km mileage. The new 2025 model of the same car is priced at SAR 233,000. Assuming a depreciation rate of 10% per year, the car's value would decrease as follows: 1st year: 233,000 * 0.9 = 209,700, 2nd year: 209,700 * 0.9 = 188,730, 3rd year: 188,730 * 0.9 = 169,857, 4th year: 169,857 * 0.9 = 152,871, 5th year: 152,871 * 0.9 = 137,584, 6th year: 137,584 * 0.9 = 123,826. Considering the car is in average condition, we might need to reduce the price slightly to account for wear and tear, leading to an estimated price.
