I like the lights and the new 6 speed auto select transmission. Recaro seat option is nice. I am waiting for the 2015 gt.The loan on my 2010 finishes then. Remember the 2013 is still the 2010 version car, 5.0 excep ion and subtle changes. The 2013 gt 500 is like a new mustang mechanically. 5.8l carbon fiber drive shaft. New suspension upgrades and 202 mph. THIS GT 500 DEEP IMPACT BLUE
