On July 31st, 2014, I drove my i3 REx off the dealer's lot. Its been four years now and I am as happy with the vehicle as the day I purchased it. The only significant expense was new tires. Otherwise, to this point, what ever issue I had or imagined I had, always small, was covered by my BMW dealer. I have a Clipper Creek charge unit in my garage which contributes further to the convenience of owning the i3.
The vehicle is today as it was originally advertised--a city car. That's why I purchased it with one caveat. In Southern California most, as I do, live in suburbs. So I consider it a suburban car. It whisks me from point A to pint B effortlessly and with the power to give me the maneuverability I require on freeways or city streets. The interior has not aged and the seats continue to give my bad back the comfort it needs. I am thinking about trading my i3 REx in for the sports edition but that's something for another day. I have taken one or two longish trips in my i3, but I prefer to revert to the other BMW in our family for long trips. For driving from beach to the Westside of Los Angeles or just from suburb to suburb, the i3 lives up to its advertisement..
I hope everyone has enjoyed the pleasure of owning or leasing their i3 as much as I have. I gave up two Lexus vehicles for the I3 and have never looked back.
