The Junior's design is more modern, although the three-cylinder leaves me puzzled.

The car is a pleasure to drive — you don't want to get out. The navigation guides excellently, but Polish names are mispronounced. The car doesn't have cornering lights. The matrix headlights are very good.

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.
