It is very comfortable to drive. It looks very good. The reverse camera is very good. BMW comes with great service package like free oil change for few years. It drives very smoothly and is fast at the same time.
There are not many cons for the vehicle. I usually like touch screen but BMW has a circular knob for the control panel which I do not like as much. You can get radio but no internet radio like tesla's. The tires are run flat and hard to find in many tire stores.
The 2018 BMW i3 has an average owner rating of 4.67 out of 5 which ranks it #7 of 22 other Hybrid & Electrics.
