Given the lack of specific data points such as selling prices, offers accepted, and listed prices of similar cars, I will use the new car price and apply depreciation logic. Assuming a new 2023 Mercedes AMG GT63 costs around 700,000 AED, and considering a depreciation rate of 10% per year, the car would depreciate by 70,000 AED in the first year. Since the car is a 2023 model and it is now 2024, the estimated depreciation would be 70,000 AED. Therefore, the estimated price would be 700,000 AED - 70,000 AED = 630,000 AED.
