I doubt you will be able to dolly with the rear wheels as the front flaring / air dam is too low and will be tore off soon or later. Simply jack up the rear of the car as high as it would be if on a dolly. Then check the front to see how close the front flaring/air dam is to the ground. Remember it will be even closer going thu a dip. We had the same problem with our BMW. Had to use a trailer with all 4 off the ground as they do not make base plates or trans pumps for the these cars either. We finally got rid of the BMW and went to a Ford C-max Hybrid as it could be towed 4 down. Using the trailer was a PITA to store when in a park. 4 down is the best way to go IMHO!
