LOL... Wrong again! The 2015 STOCK Mustangs were not available until Oct of last year... So really only maybe 6 months of true 2015 Stock mustangs. 2016 will be a FULL year production so that will allow Saleen to get there hands on chassis's a bit better. Like I stated the other day, the first of the 2015 Stock mustangs were anniversary cars which would not be used for the Saleen. So 2016 will make a HUGE difference over the 2015! Regards :)
