Just like today, back in time if you wanted to have a racy looking high-performance car on a limited budget, modifying an older car was a path often chosen. Up until the mid-1920s stripping a car of its original bodywork and building a lightweight and more aerodynamic “speedster” body for it was a popular way to go. With less weight to carry around and with reduced aero drag an automobile could be turned into a faster machine.
The owner of this Packard either purchased this one already completed or converted it himself or had someone do it for him and ended up with a very sporty machine. For a more refined result, often the frame would be cut and shortened which improved the handling and eliminated, even more, weight.
We will leave it to the experts to identify just which series Packard this is and what year it was originally manufactured in. The image is courtesy of Antique Automobile Photographs.
