9. AMC Matador X (1974)
When the Javelin AMX was discontinued, AMC was left without any muscle car in their lineup. So they quickly decided to introduce the Matador X. The Matador was redesigned for 1974 and featured a signature coupe body style. The company presented the “X” package, which could be had with 360 V8 or an optional 401 V8 with 235 HP (via Old Cars Weekly).
Regardless of the dress-up kit and big V8, the Matador X wasn’t any faster than the Javelin and the option was killed after only one year as a result.
