That is not correct. While it is true that is has a solid rear axle suspension; actually, the current Mustang chassis is a "watered-down" version of the Jaguar "S" type and recent Thunderbird. The 20 year old - pre-2005 - Mustang chassis has nothing in common with the new one.

Nonetheless, the new Challenger is a far more superior automobile in many ways that go beyond the independant rear suspension. It is amazing that these two cars are selling in a similar price range - the Dodge is a true bargain for what we are getting.
