Ford used the name “Sunliner” for many of its convertible cars from 1952 onwards. This particular toy seems to be modelled on the 1960 Galaxie Sunliner, as it still has the prominent inset bonnet, and wrapped over rear wings. The attached images shows the car in an advertising illustration from 1960.

In terms of its design, this car shows Ford moving away from the highly dramatic airplane-related styling of the late 1950s (lots of chrome and high, pointy rear tailfins) and into a much more reserved and sleeker idiom. Within the next couple of years, Ford and other manufacturers would have moved entirely away from the 1950s style, into more compact, lower and simpler forms of design. However, this particular model still has some vestigial 1950s elements - including the rear fins – and as such it represents a brief interlude in US car design, where the influence of 1950s design is still apparent, but clearly, in hindsight, now on its way out.
