Hey guys, I have a few quick questions that I couldn't find answers for after numerous searches. I'm currently looking at a 2006 Tungsten Gray GT/m5 in Dallas, Texas. I am trying to gather as much info on RPO codes and options as this is going to be a 2.5 hour drive to look at the car and most likely bring it home.

The car has black leather interior, Shaker 500, 18" fanblade style wheels, and just over 54k on it to name a few details. Would that make this car a premium GT? If so, would it include 3:55 gears, or were they optional in place of 3:31's? Also, if this is a premium GT, was the mycolor gauge feature standard? Lastly, could someone provide a list, or link of RPO codes for the S197?

Thanks for any help or advice, and sorry if I skimmed past any threads with these answers in them,
Brett.
