Inside they’re twins — clever packaging, roomy rear seats and a useful boot — so the Surf’s appeal is mostly about style and a touch of driver engagement, while the standard Dolphin is the softer, smarter everyday companion. If you want best value and comfort, stick with the Dolphin; pick the Dolphin Surf only if looks and a hint of sportiness top your checklist.
