Hi,
I am a proud owner of a 33 kWh i3. I like it because it's propose made for energy efficiency. I which it had a bigger battery though.
Also, since it has a REX, and given the still growing number of charging stations, it doesn't have any real limitations has to how far or where it can go.
It's airy and open and beautiful and simple inside although I wish the seats were more comfortable. I also wish the REX version also had a heat pump instead of a resistance for heating. Outside it is arguably the prettiest city car available. I also love that it has a CFRP pass module, but that's more of a vanity thing... can't ditch the battery weight...
Greetings,
Ricardo Lordelo
