1965 Rambler/AMC Marlin
The 1965 Rambler/AMC Marlin is one of the ugliest classic cars on the road. We’re not sure what AMC was thinking when this one left the assembly line. The Marlin had a distinctive design with a long, sloping roofline and a sleek, streamlined body. A six-cylinder or eight-cylinder engine produced up to 270 horsepower, which was impressive for a car of its size (via Hemmings).
The Marlin had a comfortable interior with bucket seats and other comforts of the time. It was one of many AMC cars that failed to garner consumer interest. The ugly styling and lack of reliability were major drawbacks of a brand that was already struggling.
