I recently bought a used 2024 Mustang EB convertible premium. I do have the 200A package.
I have 2 questions.

1. how do I know if I have the S550 or S650?
2. how do I change the sound of the muffler? There is an icon “Sound” but it is grayed out. Am I looking in the wrong place?
   Thanks

I have a 2024 Mustang Ecoboost. What is a good sun shade shield to use?

I’m looking at a 2023 mustang eco boost, convertible.
I am wondering if there are any issues with the motor, transmission or turbo issues. This car has ~55k+miles.
Can anyone lend any insight?
Thanksw
