Very important note,Check under the front bumper of your smartie, and make sure that the two(2) little feet that hold the air dam to the front bumper are properly inserted in the bumper!! Mine were not and at 70-75 mph on I-85 there was this very loud bang and flat tire sound . When I stopped and looked, the front of the smart car bumper was loose and the air dam was peeled under the car!! It ripped off the two brackets that hold it to the frame and it is ruined. I got back to the house and used aircraft tape (very srong duct tape used on planes)to put it back together. Dealer will replace it,if and when they can get it!!So its worth the look to see if all is OK. Could have been loosen if you back up off those concrete parking stops used in shoppins mall's . p1nball

PS You might want to use aircraft tape on those two pieces so they don't come apart!!!!!
