Very little. What would you do? I would: Keep working on the seats - after months telling everybody here how great the premium perforated seats are, I'm beginning to prefer the Recaro Next Gens in my 2016. Give us more seat options. Sound insulation Do something to eliminate the plasticky silver material on the interior (screen bezel and in the door sill). Upgrade the appearance and feel of the door sill leather and the door handles. Sound insulation. Soft close, self presenting doors More storage pockets Upgrade center console appearance. Super trick road sensing suspension to make the ride even smoother as an option. Even more effective ventilated seats. Coat hooks, better mirrors.
