Calling a soft-top a coupé is an unusual choice, but then the convertible version of Rolls-Royce's Phantom limo is pretty unusual full stop.

For starters, it costs more than a third of a million pounds, so it's always going to be an ultra-rare beast. Plus it features rear-opening doors, an interior that's more crafted than built, and an exterior design inspired by 1930s yachts; you can even specify it with optional teak decking.
