1965 300L
The 1965 300L was the final year of the traditional letter series. A complete restyle, with crisp lines, slab sides and a tall "greenhouse"—styling cues introduced by Elwood Engel when he succeeded Virgil Exner as Chrysler's styling boss—brought a sleek mid-1960s linear look to the cars, and dropped the panoramic windshield that had been used since 1957. The cross-ram engine was no longer available; the 413 cu in (6.8 L) engine with regular carburetion and inlet manifold was the only one supplied. Practically every feature on the 300L could be ordered as an option on the regular 300; the only absolute difference was the "300L" badges. A total of 2,405 coupes and 440 convertibles were sold.
