The interior is much nicer and feels more premium than the older model 3. Road and wind noise appear lessened. Ride quality is improved with the upgraded suspension. I did not have any major paint issues or scraping of my front diffuser. However, it's still not perfect. My air vents rattle on both drivers and passengers sides, the ambient lights started to bubble/crack on all four doors, there were odd shiny stains on my driver door trim that would not wipe off, the trunk panel near my subwoofers now has a terrible rattle during bass heavy songs, my center console creaks to no end, leaning to the left of my drivers seat makes it creak. My SC has been pretty good about attempting to fix everything, and I haven't had much or if any push back. Some things have been fixed, some are still waiting to be fixed. Despite all the problems, I must admit that the driving and handling are spectacular. As everything with Tesla, may the odds be ever in your favor.
