This is a rare 300K (one of the ‘Letter’ series 300s) two-door hardtop coupe, finished in Roman Red with cream interior and showing 45,745 miles on its clock.

Regularly restyled and updated throughout the 1960s, the ‘Letter’ series had arrived at the 300J by 1963, featuring all-new styling that would be carried over to the 1964 300K range.

By this time Chrysler's 'Letter' series hot-rod was powered by a 413.8ci, 6.8-litre V8 producing 390bhp.

Production ceased in 1965, the 300L being the last of this highly collectible family of high-performance coupés and convertibles.

Accompanying documentation consists of a South Dakota Certificate of Title; the purchase order; and a copy of Gesswein's advertisement.
