To estimate the price of the 2018 Ford Mustang, I focused on the selling prices of similar cars. The most relevant data point is the 2018 Ford Mustang 2.3L I4 coupe with 84320 km, which had an offer accepted at AED 50000 on 7 Feb 2024. This is a close match in terms of year, engine, and body type. Another similar 2018 Mustang with 90000 km had an offer accepted at AED 49000 on 4 Jul 2024. These offers are the most recent and relevant, suggesting a price range around AED 49000-50000. The selling price of a 2018 convertible variant at AED 59000 on 15 Jul 2024 is higher due to its body type. Considering the target car's higher mileage of 100000 km, I adjusted the estimate slightly lower than the accepted offers.
