most likely because most companies depreciate (expense) capitol assets like car-body tooling for 5 years 2014-2009 = 5.
This is also the most likely reason all 2015 challengers are lower-priced and the hellcat is priced more affordably than many anticipated. Chrysler-Fiat is still cutting a fat hog selling them at these prices.
Thanks to the nice long run for this body style -everybody wins.:grouphug:.except the competition!
