The engine bay looks so clean and looks like something a basemodel car would have, good in a way, at least it's not obviously a performance model, more along the lines of a tamed sleeper.
CLA45 AMG Exhaust note in this video sounds much better, im sure there aren't many 4 cylinder turbo's that will sounds like it. Closest things may be the Fiat 500 Abarth and Mini Cooper S JCW
