The model, starting at £33,645 for the less charismatic 2.3-litre Ecoboost-engined Fastback, is admittedly not the kind of stupendous bargain that will have Focus ST owners upgrading in droves, but it still registers as plenty of car (and power) for the money.
The V8 is a different matter. It simply isn’t possible to have more cylinders or output for the £38,095 starting price. And that is the kind of simple equation that compels the right-minded buyer to sit up and take note, whatever the weather.
Outright speed or dynamism, as we’ve noted, is a different subject – and the fact that the same money buys you a Volkswagen Golf R, a BMW M240i or, indeed, a new Focus RS means that the Mustang is never going to be a two-a-penny prospect on British roads, particularly when you take its thirst (an average of 18.9mpg in our hands) into account. Tellingly, it is cheaper than the BMW M2 and the latest Audi RS3.
Its likely scarcity, though, is a good thing. It not only ought to keep used prices buoyant but will also serve to remind its owner that the decision to seek out the Mustang for its clear ability to stand out from the crowd will not have been in vain.
