If you don't mind, please do keep us posted. I am wondering how much the taxes, customs, registration fee, etc. end up being on top of the prices seen under "other Europe". And of course how much hassle the paperwork ended up being...
I tried to calculate registartion fee (tax) once and also the "performance tax". One of these taxes (not sure which) had hybrids as a category, but not EVs, the other had no discounts for non-ICEs. Calculating the insurance should also be "interesting" as I am sure the car is not listed in the standrd online calculators.
Did you look into charging stations in Hungary? I could only find evidence of a very few. Maybe 20 in the country. A couple around lake Balaton, 1 in Miskolc and a few in Budapest - but I see the 1 EV spot close to Gellert tér occupide by ICEs all the time. And as far as I could see that's only a 11kw charger by ELMU.
