Cadillac: my mates' cadillac

a friend of mine has a '55 - '57 cadillac, i'm sorry i'm no officionado!
anyway he recently tried to move the car into storage for the winter but
the car dumped all it's power steering fluid; due to circumstances the car
sat for a few days but when he tried to move it again, the whole car
wouldn't move, no drive - nothing. previously the car had been driving
with no faults for years. please could someone help as the guy is at wits'
end? ta much - spaceman spiff

problem! thanks again and merry xmas and happy new year to you all -
