What Fun
 This is a super vehicle.We just purchased the car and have absolutely loved driving it.The power, braking, steering of this car are awesome. It's like riding a high tech roller coaster, smooth and on a rail.The iDrive is cool. It IS very easy to use once you navigate thru it a few times. We got this car w/out the sport package and were told it did not come w/run flat tires.This was not the case, as tires marked with the letters RSC circled are run flats. (No spare tires in this vehicle.) Also, the convertible has more head room in the rear seat than the coupe. I am 6' and 210 & I can sit straight up w/some leg room. Coupe I have to tilt my head.Trunk has more room w/top down,then any other in its class.
