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 2023 Tata Xenon Standard pick-up has a price of 100,000 AED, and considering a depreciation rate of 10% per year, the car would depreciate by 10,000 AED in the first year. Therefore, the estimated price for a 2023 model in 2024 would be 90,000 AED. Additionally, considering the high mileage of 100,000 km, I will further reduce the price by 10,000 AED to account for the wear and tear, resulting in an estimated price of 80,000 AED.
