What’s this car’s USP?

The roof. Its folding mechanism is a minor work of theatre. But you need to be below 6mph to operate it, and things get blustery at speed with it folded. The roadster is a better, easier-to-use cabrio, if not as cool to look at. Back seats that accommodate small adults and a decent boot. Alcantara interior bits, a power and torque curve display on the dash and stability control with a track mode prove this is the drivers’ choice here.
