 FAKE: When Kenny pulls into the gas station where Gene is working to  pay off the repair bill on his fathers car, the wing vent windows  show signs of bubbling between the laminations. Since this movie was  set in 1956, a 1955 automobile (the Chevy convertible) wouldnt show  this result of the aging process. Its a phenomenon of safety glass  that happens over several years of exposure to the elements. Also,  there are no rubber window bumpers at the top of the driver and  passenger side window tracks (directly behind the wing vent  windows).
