For the sixth generation, the Country Squire again shared its doors with four-door Ford sedans.
While the roofline of the Country Squire was shared with the Mercury Colony Park, the two model lines shared different bodywork below the window lines (including front fascias and rear quarter panels).
In a major styling change, full-size Fords adopted vertically-stacked headlamps, raising the hoodline and enlarging the grille.

In a design change that would last through its 1991 discontinuation, the 1965 Country Squire replaced the third-row rear seat configuration for two (optional) flat-folding rear seats facing towards the center of the cargo area, expanding seating to 10 passengers.
  Coinciding with all full-size Fords, the Country Squire adopted two-sided keys for 1965, introducing a valet key (while unlocking the front doors and starting the car, the key would not unlock the glovebox and rear cargo door).


Following a minor grille update for the 1967 model year, the Country Squire underwent an exterior update for the 1968 model year.
Coinciding with its becoming a counterpart of the Ford LTD, the Country Squire adopted its split-grille front fascia, adopting vacuum-operated hidden headlamps; as a fail-safe, the system retracted the headlamp covers if engine vacuum was lost.
While the feature was shared with the Colony Park (and its Marquis counterpart), the redesign marked a significant differentiation of front fascia designs between the two model lines.
 In another change, the taillamps switched from a square design (derived from the traditional Ford round taillamps of the 1940s and 1950s) to a vertically-oriented rectangle (a design used to 1991).
