Glad you are enjoying your SS!
I am in the same boat as you, I had the extended warranty included in the sale of my car, as that was important to me.
So far, I have had the windows tinted at 20% in the rear, 35% on the sides... I didn't go for the billet bowties, I went for the vinyl ones instead, that way they are cheaper, and also you can switch them out as often as you want if you want to change up the color.
I added colormatched bowties to the wheels and most recently a K&N Intake system. My favorite mod was from Scott Settlemire and John Fitzpatrick tho! (seen in the intake pic)
And I had the obligatory personal plate!
I will be considering an exhaust in the future and the Heritage Grill as well. Pics for fun!
