John J the California special is a GT option they had the CS (California special) in 68 and brought it back in 2007.Here is the description I copied from the Ford webpage.
*********************************************
It�s all the things you want in your Mustang GT plus a little extra inside and out to make it �special.� It�s called the California Special and it will be available this summer.
To get the California flair you start with a GT Premium package. The California Special then adds unique California Special Dove or Parchment ""GT Leather"" trimmed inserts and Black with Dove or Black with Parchment interior color scheme. The front and rear floormats include the special Mustang badging.
Exterior accents include side scoops and unique front and rear fascias. The front fascia has a larger air intake and is actually 1.5-inches lower than the standard GT. The rear fascia is also cut differently with less tuck-in.
The polished aluminum wheels are 18-inches with a bright machined rim and are wrapped with Z-branded all-season tires.
Bright rolled exhaust tips and unique tape striping add the finishing touches.
