It won’t swallow the weekly shopping or ski bags, but for anyone after pure driving fun and sun-on-your-face weekends, few cars match its sheer charm and value.

The MG4 seems more versatile to me than the Dolphin, which relies mainly on design. The MG4 has proven itself and remains an excellent used option with low mileage.
