I'm considering trading my 5.0 for a 2013 GT500 I don't want to pay 60 something. I notice that brand new 2012's are going somewhere in the higher 40's. What do you guys think the price will be on a 2013 when the 2014's come out. Or should I was consdering twin turbo charging or supercharging my 2013 gt. What do you guys think?
