Interestingly, the fact that more recent EVs have much longer range isn't enough for me to make a switch. Like you, I've driven a "short" range EV for years now and have learned I just don't need more range. It would be nice, but not needed. Same with DC fast charging - a nice option, but I never once used it in 6 years of driving my LEAF. There are three main reasons I haven't switched to a different EV:
* I live in Austin and I have never once seen another B class since I bought mine. I do like that it is unique.
* My B was paid off about 6 months after I bought it. Hard to justify spending money when what I really want doesn't exist, which leads to -
* No one makes what I want. I want a GLA that is fully electric (who knows if/when MB will bring the EQA to the US) or an Evoque EV. Teslas are nice but they don't offer an opening sunroof (3, Y), ventilated seats, head up displays, or even actual leather!
The Kona comes closest to having all I want in a size I want and the styling is nice. But you get inside and it's all hard plastic. My MB with the interior package is just so much nicer. EVs won't really take over the market until there is a wide variety of models to suit a wide variety of tastes. Range.. meh. People have learned they don't need 300 or even 200 miles.
