You've identified the Mustang, because it's a pretty unique set of attributes for it's cash. You're also clearly aware of the obvious German rivals.
For £50k, the less obvious potentials could include the new Renault Alpine and Alfa 4c, though clearly they fail miserably on the noise and hp levels. They would however be a good deal lighter and potentially more interesting to drive (though I'm personally doubtful).
If the budget can be negotiated, maybe a Vette
