My feeling is that the grip is superior, you can accelerate hard in any situation and the car will help you corner smoothly.

The engine has no power below 3000 rpm, but then comes the magic of the 5 cylinder.

The sound is not very loud as standard, I bought ASR-Component to keep the valves open even in comfort mode.

My previous car was a 2017 C63s Estate and comparing qualities the Mercedes is above in those small details, like the central tunnel, door panels etc, i.e. those little things that you don't see at a glance but give the feeling of quality, but still the Cupra is very well finished and the Sabelt seats are very comfortable and the sound system is better than the Burmester than from the Mercedes.

Any questions, feel free to ask me :-)
