The process was first used by race car builders to cheat on the propositions and then it was accepted by anybody who wanted maximum out of their car.
Muscle cars continue to be a popular choice for drivers young and old. They make a bold statement on the road, whether they are a new model or a classic one. Ask any driver, and they can probably name their favorite model of a muscle car. And, even if they can’t afford to buy one, at least many car shows feature them.
