Teslas on the road today all look like they have a stale design compared to new offerings from other manufacturers. I think it’s a fair point even if they are continuously updating the internals.
It's fine to argue you think they have stale design (an opinion), but that's very different from saying their average model is 9 years old, and comparing that to other carmaker's average model age.
Yes, not all customers buy into the original [external] design.
Personally I think it's a low-rent imitation of Mazda, so a refresh would have been nice.
For all the "but the insides have been upgraded/revamped!!" messaging, it's just confirming that they're too cheap to improve, or just change, the outside.
Also they did just update the Model 3 (looks great!) this year so they are moving in the right direction. Did you see this refreshed look on the Model 3?
Porsche has changed the 911 body, quite radically in fact, if you side-by-side anything 1980s or before with 2012 or later.
But what Porsche does very well is introduce new platforms every few years. It's still a 911 but a new generation, that generates excitement and new sales. Then a few years into each cycle, it releases various sub-specialties and performance variants -- the RSes, GTs, Turbos, etc. Yes this often means at the very end of a platform's life sales drop (in anticipation of the next version) but overall its clear that Porsche has been extremely successful with this release model, which I think the other German carmakers emulate, like BMWs 3-series.
