I remember years ago driving a Brabus smart coupe thing that had a tuned three cylinder lump in it; the gearboxes was hideously slow witted, but when you were ringing the nuts off it it (somehow) manhed to sound like a Ferrari 355.
I'm genuinely impressed with the sound of that little BMW engine.
Gone but not forgotten:
325i M Sport (E92), Black Sapphire, Coral Red Dakota, 19" 225's, Seat Heating, 6FL and de-badge
Replaced by 6.2 litres of AMG powered C class.
