The top 2 pictures show the Meteor Rideau 500, both 2 door hardtop models. Once again, like the 58 USA Fairlanes, the Side Trim is very similar, if not exactly the same as the 58 USA Fairlane 500's. The Blue and White Hardtop doesn't have the Rectangular side trim on the rear quarters, while the Gold and White one does. Is the second car a Spring model?
The last photo shows a closeup of the Grille that is in these 1958 Meteors.
