I dislike Musk and Tesla’s interiors enough that I’m going with a different brand, that said…
The big answer is still the charging network, even with Telsa opening up to NCAS from other manufacturers. If you buy a non-Tesla NACS car, you still only get access to about 1/3 of their network. And the Telsa’s network is still usually much faster and more reliable than its alternatives.
I would also argue that the price to range ratio is still pretty compelling when compared to the competition.
