TBH, I feel like the Challenger and the Mustang are two totally different segments.
The Challenger is a comfy, big, v8 cruiser (aka more like a true Muscle car) whereas the Mustang is a smaller, sportier car.
Similar, but very different.
^^ he gets it.
45 years ago, the mustang and Mopar E bodies were in the same segment. Today, Dodge is carving its own niche.
