If you're happy with it, enjoy it! These cars came fast enough and enjoyable enough from the factory for most people. I didn't start modding until I had the car for almost 2 years, but then I made up for lost time LOL. Glad you are happy with your mustang, and glad you got to be where you want with it! That is the goal of everyone on this forum, to be where they want with your car. Enjoy your ride!
