Hello there. Yesterday I got my CPO 2013 P85+, and I am quite unhappy with it. Yes it is fast, but that is it. Neither the technology nor interior appointments impress me. The "ultra super premium sound system" is a joke. But what really is killing my desire to drive this car daily is how noise it is in the parkway. The 21" rims and low profile tires certainly do not help and I will replace them, but really this car needs proper soundproofing. There is nothing I can do with the thin single pane windows, but did anyone here attempted to soundproof a Model S? I believe that replacing carpets, under-mats (if any), and adding proper noise damping would cost $2k or less. That would be a lot less than trading in this car after two days. Or having a $60K paperweight in my driveway. Off course if someone in the area is interested on alleviating my pain, I am a motivated seller.
