Who can help – different purchase criteria – 911er sound and smell – Thank you 🙂

Hello everyone, Sound: I am rather someone who likes it a little bit quieter in contrast to the usual Porsche fan. Can you tell me which Porsche 911 was equipped with a quieter sound from – to )? I would like to drive such a model sometimes …. And is it also switchable off with the new models of the additional sound ? Interior fragrance: I tested a new 911 Cabrio 4 S a few days ago. It was a completely new car. I am furled that the driving z Eug extremely after plastic / fragrance … smelled. An acquaintance told me that the odorous substances are in the meantime extra into the interior equipment – artificial materials and evaporate permanently? White jemadn of you more about it? Does this smell disappear sometime? After what time? Does the stench come from a specially applied spray, which disappears after a while or does it drain out of the artificial material of the interior decoration? From which year is this so? Thanks to all Gruss PB
