To estimate the price of the 2021 Ford Mustang 2.3L I4 Ecoboost convertible with 63000 miles, I considered several data points. First, I looked at the selling prices of similar cars: a 2022 Mustang GT 5.0L V8 sold for 78000 AED, a 2023 Mustang 2.3L TC I4 sold for 103149 AED, a 2020 Mustang 2.3L i4 TC sold for 44000 AED, and another 2020 Mustang 2.3TC I4 sold for 52000 AED. The most relevant comparison is the 2020 Mustang 2.3L i4 TC with 32400 miles sold for 44000 AED and the 2020 Mustang 2.3TC I4 with 74133 miles sold for 52000 AED. Given the higher mileage of the target car, its value should be slightly lower. Additionally, an offer of 90000 AED was accepted for a similar 2021 Mustang 2.3L I4 Ecoboost convertible with the same mileage, and it was listed for 93500 AED. Considering these factors, I adjusted the estimate to reflect the market conditions and the car's condition and mileage.
