There’s no option of a wind deflector, but windows up, at sensible speeds, and it’s relatively free of buffeting. Your locks will be gently tousled by the passing breeze, while you wonder why the image in the interior mirror is wobbling as you pass over bumps in the road.
The inevitable answer is that, along with the metalwork, so too has disappeared a large portion of the body’s torsional rigidity. The low-speed ride, mind you, is acceptable - at least as good as in the hard-top. Perhaps the flex in the chassis allows a little more compliance than the coupé.
Should I buy one?
The compromises with the roof and engine leave the Mustang convertible in a slightly odd place - at least with this engine. It’s no better to drive than plenty of other convertibles at its £33,000, arguably no better looking, quite large on the outside compared to its size on the inside, and is a wide car to thread around.
You’d have to really, really want your four-cylinder convertible to be a Mustang to choose one. But it can also be had with the V8 (£37,005), which I suspect would pitch some of that allure back into it. There’s something to be said for some open-top V8 woofle. Certainly, what comes through the speakers can’t match it.
