The first Mustang rolled off of the assembly line back in 1964. Now to celebrate the five-decade milestone Mustang has announced the 2015 Mustang 50 Year Limited Edition ($TBA). Now if you want to pick up one of these bad boys, you’ll have to get your name in fast because only 1,964 will be made. This limited edition Mustang will be based on the 2015 Mustang GT fastback with an upgraded performance pack. It will have louvered rear quarter windows and chrome highlights which can only be found on this model. As far as performance, the 5.0-liter V8 will deliver 420 horses and 390 lb-ft of torque which isn’t bad for an old man.
