Jeez, guess if the V6 isn't a muscle car what did us V6'ers buy?
The Camaro should be a muscle car regardless of the engine... it's just the class it belongs in. Same goes for the Mustang, Challenger, and the classics as well.
That's the problem with one car having different engines, the people who own the V8's are always looking down on the V6's, and the V6's are always looking down on the 4-bangers.
