Query: High Performance let down.

The American Muscle Car series as a whole are a big disappointment. The material is poorly researched and subsequently, poorly written. The historical data is always very general and if you are well versed with the car at hand, you will not walk away any wiser as a result of these videos. The 3 cars that are profiled on this tape were on other American Muscle videos in the past so know I have more videos on the same car.
