Decided to sell my S and looking to get a 3, I don’t particulary like the 3 since I find it feeling quite cheap so it isn’t really a switch I am looking forward to. But since we don’t really need a car to begin with it doesn’t make sense to spend the extra for the S anymore. Wanted to go for a P to at least give me something fun but after testing P/LR AWD back to back the tire noise from the 20” was unbearable so ill have to settle for the LR AWD with acceleration boost. The big question is with the lack of a HEPA filter in the 3, since I am allergic to pollen I loved the clean air in the S. No smells and no pollen, how is this in the 3? Do you smell anything if you are behind a dirty diesel truck spewing out black smoke? While going past some sort of smelly plant or fertilized farmland? Any pollen getting in?
