I have a 1979 280E, I reversed her into the driveway this arvo and forgot to straighten the steering wheel before turning her off. The Steering is now locked, the key won't turn and steering wheel won't move. I have done this twice before in the 3 years I have owned her, both times I have asked for help from a strong man, they have given the steering wheel a sharp twist and everything has freed up. My husband has tried but can't move it this time . Help !!!
