To estimate the price of the 2020 Lamborghini Huracan LP 580-2, I started with the new car price for the 2025 model, which is SAR 1,020,000. Given that car values depreciate by approximately 10% per year, I calculated the depreciation over four years. The depreciation factor for four years is 1 - (0.1 * 4) = 0.6. Therefore, the estimated value of the 2020 model is 0.6 * 1,020,000 = SAR 612,000. Considering the high mileage of 100,000 km, which is significantly above average, I applied an additional depreciation factor of around 10%, resulting in a final estimate of SAR 550,800.
