...finally bought my Karma 4-5 months ago. It is, hands down, the most fun I've ever had in a car.
I've had a few minor issues--a heat shield that rattled, ball bearings in the wheels that made a clicking noise when making a hard turn, and some wind noise in the backseat at freeway speeds. Those are the only problems I've had with my Karma, and all three were relatively quick fixes at my dealer.
I've been totally pleased with my Karma. My only regret is that I delayed the purchase for months while I tried to figure out what was going to happen with Fisker and whether or not there would be deals to be had toward the end of 2012. I wish I had not waited so long. And now, as an owner, I wish everyone else would jump in because the water's just fine!
