Picked up my '13 CPO GT today! Been in and around Mustangs all my life, but this is my first one. I'm coming out of a 200hp Sonata, so needless to say I've got some adjusting to do.
Got one pleasant surprise - the car already had GT500 axle backs installed. I had planned to put those on soon, so that was cool. No other mods, other than a light window tint.
I picked it up in Atlanta and drove back to Birmingham....averaged 26 mpg. Not bad.
Looking forward to some 5.0 fun.
