I think you're underestimating how much hacking was required to get Model S into production, and how much that causes the design to generally feel cheap. Changing suppliers over and over, rushing new designs to solve problems in other systems, that kind of stuff leads to subtle incompatibilities in the overall architecture. Model S is basically a V1 car. Audi has made a dozen generations of vehicles, each time getting another chance to refine the design. The Model 3 is a big leap forward in fit and finish, albeit in a simpler design, without "premium" flourishes. The next gen Model S will be Tesla's first real foray into designing a serious premium interior on purpose, with experience. It'll be interesting to see how it does.
