Chevrolet Cavalier Z24
The Chevrolet Cavalier Z24 finds itself among the worst muscle cars due to a struggle to deliver the high-performance experience expected from the Z24 name. Introduced in the late ’80s, the Cavalier Z24 featured a modest powertrain and uninspiring design, failing to capture the excitement associated with true muscle cars. Its lackluster performance marked it as a disappointment in the eyes of enthusiasts, making it a forgettable chapter in Chevrolet’s muscle car history.
