As an owner of the Fisker
As an owner of the Fisker Karma as of June 20th, I just love it. I drive almost exclusively in stealth (battery only) mode. So far I believe I have used less than a gallon of gas with 286 miles traveled, and when I get the level 2 charger installed, I expect to use even less.
In my opinion the car is a pleasure to drive and is just gorgeous. As a bonus, I am not even close to having my first visit the gas station with it.
