One such was the De Tomaso Pantera (Wikipedia entry here) that was sold in the U.S.A by the Ford Motor Company. It wasn't the lowest of the low, but its design by Tom Tjaarda incorporated many of the styling and engineering elements fashionable at the time for cars of that class. For instance, the engine was placed behind the passenger compartment, but ahead of the rear axle line. The front of the car tapered (in profile) essentially to a point. Most body surfaces were nearly-flat facets, the overall design being an assemblage of these.
The Pantera's styling therefore can be characterized as simple, with form being the dominant visual element. There was virtually no ornamentation.
