To estimate the price of the 2021 Lincoln Corsair I4 2.0L Turbocharged Premier (Base) with 77500 km mileage, I first considered the selling price of a similar car: a 2021 Lincoln Corsair 2.0L STANDARD with 64336 km sold for AED 108791.5 on 2023-10-22. Given the higher mileage of the target car, I adjusted the price downwards. Next, I looked at the listed prices: a 2021 Lincoln Corsair 2.0L STANDARD with 64336 km listed for AED 127990 and a 2023 Lincoln Corsair 2.0L RESERVE II JET with 3304 km listed for AED 169990. Considering the target car's higher mileage and average condition, I further adjusted the price downwards from the selling price. Factoring in depreciation and the condition, I arrived at the final estimate.
