10/17   The manual for my car says that I should get the air bag system
        checked 10 years after manufacture of the car.  And it's been 10
        years.  So, how important is this?  How expensive is this?  And
        where would I get this done?
        \_ uh... maybe you should call the dealership
        \_ important if you expect to have airbags protect you.  there
           are electrical contacts to corrode, highly combustible
           chemicals to degrade, fabric to age, sensors to fail, and
           no chance for a practice run.
