I bought my son a 2013 Mustang GT with the Track Package and I can't believe how much car we got for $35 OTD. He says it is a little different than his 1996 Grand Marquis. :lol Ford did a great job with the option packages. You can get all the performance-oriented parts and electronic doodads a la carte. The Torsen differential that comes with the Track Package is out of this world. Those of you getting the Torsen with the 2013 GT500 will really like how it works on the street. Good job Ford!
