It shows too. There's some parts on my Performance that just don't feel as high quality as the new car. I don't have any fit issues with either car, nor did I with the 3, but the interior felt even cheaper in the 3. It's like the seat material was more rubbery. My Performance is a late Y before the redesign though and I think they have been upgrading materials year by year instead of waiting for refreshes. I have seen bad fitment earlier Teslas though.They've actually graduated to using automotive grade parts, and by all accounts their panel misalignment and structural leaks have been reduced.
