I'm no Tesla fan, but having longevity in car models is a good thing. My fun car was built by VW in Germany for a decade and then by VW in South Africa for another decade; parts availability is great.

In today's marketplace of very samey cars, models that work should probably last a decade or more.

That said, Tesla could have built out a couple more styles, such as maybe a minivan/workvan/delivery van, although van sales can be pretty cyclical, and Tesla parts and service was (is?) notoriously poor in some cases, so I dunno if commercial users would be interested.

I like what Rivian does, an EV skateboard where different bodies can be bolted on top with little design modification. I could see them moving into the crossover market just by shortening and lowering the frame.

Yeah but a decade ago is still a decade ago.

You see one Tesla, you have seen every Tesla. Colors? The same too.
