These are 1965 model year cars. There's a 1965 2-door full-size Mercury in black front and center (right behind a Lincoln - which looks very similar because Ford specifically marketed the Monterey/Montclair/Park Lane as being in the "Continental Tradition).

1965 Mercurys are single-year cars. The body style changed in 66 thru the end of that generation in 68.
