What Car? says...

The DS 3 is the smallest car in Citroen’s premium DS Range. There's no five-door option, just the 3dr hatchback and this Cabrio derivative, which has a scrolling fabric roof between fixed arches.

The most critical rival is the Mini Convertible, which is similarly priced despite it being a full convertible, and having a more premium interior. Other rivals include the Fiat 500C, which doesn’t offer the same performance as the DS 3 Cabrio but is drastically cheaper, and the bigger VW Beetle Cabriolet, which also offers similarly cheerful soft-top motoring within a similar price range to the DS.
