Very comfortable. Precise steering. E35 petrol engine, 150 hp — sufficient. Manual gearbox very good and well-geared. Looks very handsome. Very large boot. Premium interior.

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.
