What dealer did you purchase from? Do the I3 not carry 4yr 50k maintiance
We leased it for 2 years from our local dealer.
On an electric car, the car maintenance is almost irrelevant. There's not much to maintain.
The big issue is the battery life. BMW warranty it for 8 years.
However the technology is evolving so rapidly that today's battery is already obsolete. Both Nissan and the Volt are offering much better batteries for their 2016 models, significantly increasing range. This just kills resale value.
