In what world? Are you naive? AMG alone is thriving their business model on loud cars. There is luxury brands like Ferrari, Lamborghini, Königsegg which are loud by design. There is muscle cars from Ford, Corvette, Cadillac etc.etc. There is loud Audis, Porsche, BMWs, Mercedes. There es even a ridiculously loud Volkswagen Golf GTI or R.
Like what?!?!
Edit: they even having a sound check feature on their websites lmao (at least Mercedes)
Edit: for reference the Golf R has even a membrane build into to cockpit to amplify its sound to the passengers.
