Because they've been out for a lot longer? If I'm right, I believe the challenger has been out for over 8 months, and the 2010 mustang is a 2009 mustang, with a minor face lift, and has still been out, for around 3 months? The camaro was almost JUST released, I don't know the date but I think within a month ago? My brother is a GSM for a Chevy store, they are 2 months worth of allocation ordered. They are selling, and theres a lot running around Palm Harbor/Clearwater.
