You are probably more familiar with the mid-sized 60s version, but the Coronet name was originally used in 1949 by Chrysler as the Dodge division's first post war design product offering.

The Triumph TR3 was a diminutive two-seater produced by the Triumph Motor Company from 1955 to 1962 (updated per comments from Jeff below). The TR3 was a roadster, not a convertible, as it was designed for open air motoring and only had a small snap-in-place rain protector with removable side shields.
