what do you think is much better about the model 3 ? no heat pump, its interior styling/fit-marmite, no hatch-back flexibility, even, exterior styling too.
Ever been in one or driven one? Perhaps ask some owners or those who have driven both what's better about it. As pointed out, the Supercharger network is a massive plus. I've driven EVs of various brands for several years including the Kona and Model 3. There is simply no comparison for long range travel, anything aside from the Supercharger network is just irritating at best. The performance, handling and in my view styling of the Model 3 is also massively ahead of the Kona. And the interior minimalism, as you say, is Marmite - but interior material qualities are pretty good in my opinion and far superior to the Kona. I think both cars look nicer in person than pictures, more so the Model 3. It's is a lovely-looking car in my opinion and more distinctive than the Kona without being over-styled.
The constant over the air updates, glass roof, large infotainment screen and efficiency also seperate the Model 3 out from many competitors. The little touches like Sentry Mode, integrated connectivity (Spotify, YouTube, Netflix etc.) are nice. And Autopilot is very pleasant to use, when used properly and with limitations understood. But I don't suggest anybody takes my word or anybody else's for it. Go for a test drive when you can, if you're genuinely interested. It's a lovely car in many ways and has rightfully converted many avid petrolheads. Something you won't see the Kona doing.
