In the spring of 1964, the LeSabre appeared slightly revised and again in four body styles with the later 60s Coke-bottle type body available in base and a more luxurious Custom trim level the LeSabre was the entry-level model at Buick with the lowest base price. Built as a four-door sedan (with B-pillars and hardtop), as a two-door convertible and a two-door coupe (also with hardtop). The five-door estate cars formed the independent series. It was now fitted with smaller engines with only 4916 cc and 210 hp (154 kW) used along with larger options. There was also a three-stage automatic transmission along with four-speed manual or 2 speed autos. Wheelbases remained as the previous model at 123 inches long.

1965 there were the technically identical models in standard and custom design, the Cabriolet was available only as a custom version. The styling of the vehicles was designed a bit more angular.

The following year, the station wagons formed their own series called Sport Wagon, and the two-door coupe was designed as a hardtop. A clear facelift provided for a strongly contoured radiator grille and a hip swing over the rear wheel arches. In addition, a larger 350-cubic-inch V8 engine with 5572 cc and 220 hp (162 kW) was used. 

Without major changes, this model series was further developed in 1967.

In 1968, there were more stylistic adjustments, rectangular surrounds for the round twin headlights and grille. Again, the engine power was increased, this time to 5735 cc and 230 hp (169 kW). In 1969, the inner body structure was still the same but the front end was restyled slightly smoothed in the otherwise technically unchanged vehicle asides from body panel changes, along with new federal safety laws head rests and steering column locking system now became standard fitment across the range. By 1970 a large full-sized Estate station wagon was now offered.

During these six years 937.856 copies were made by the end of 1969.
