Given the lack of specific data points such as actual selling prices, offers accepted, or listed prices of similar cars, I will use the new car price and apply depreciation logic. Assuming a new 2019 Mercedes S650 Maybach 6.0L Turbo Charge V12 RWD (Top++) costs around 1,000,000 AED, and considering a depreciation rate of 10% per year, the car would depreciate by approximately 50% over 5 years. This results in a depreciation amount of 500,000 AED, leading to an estimated value of 500,000 AED for the car in question.
