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.

The Mercedes is superior to the BMW 1 Series in (almost) every respect. The 1 Series BMW, however, is designed differently, so everyone can pick out what he/she needs.
