Given the lack of specific data points such as selling prices, offers accepted, and listed prices for similar cars, I will use the new car price and apply depreciation logic. Assuming a new 2020 Porsche 718 Spyder had an approximate price of 400,000 AED, and considering a depreciation rate of 10% per year, the car would depreciate by 40,000 AED each year. Over four years, this totals a depreciation of 160,000 AED. Therefore, the estimated price would be 400,000 AED - 160,000 AED = 240,000 AED. Adjusting for the average condition and mileage, I estimate the market price to be slightly lower.
