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.

Mercedes A Class Saloon

The Mercedes A‑Class Saloon blends compact practicality with premium flair, wrapping a surprisingly spacious interior in a slick, modern package that feels more grown-up than its hatchback sibling. It’s an ideal choice for city drivers who want Mercedes polish and cutting-edge tech without the ostentation of a larger saloon, and it even manages to make the daily commute feel a little bit special.
