I generally consider tuners to be import owners that change nearly everything about their car: interior, exterior, and performance -both straight line and handling.

A muscle car is a domestic that has a big V8, huge power and torque, and handles well enough to head back and make another run at the drag strip.

You can't make something a muscle car. It either is or it isn't. But there are a lot of options to make something into a tuner.

Thats how I look at it anyways.
