What used Ford Mustang coupe will I get for my budget?
About £23,000 seems the bottom line for a Mustang of 2015/16 vintage. This buys you 2.3-litre with an average mileage for the year. Expect to spend between £25,000 and £28,000 on an early V8 GT or a 2017 car, and around £30,000 to £35,000 on a newish 2018 or 2019 car, bought from a franchised dealer.
