@isellcorvettes Any chance you could give us the price of the GS (coupe and convertible)? The price hasn't made it to the Chevrolet website yet (as of this morning).
Did you set your PDR to overwrite when your memory card is full? @anthonybutler@ro
There is also a little slide lock/unlock on the SD card. Make sure that is fully in the unlock position.
Do you have the Z51 option? that left button looks like you can go toggle through the various traction control settings when in Track mode (wild guess).
You should also consider doing the Corvette owner's school. Many of us have done it and enjoyed the 2 days of fun on the track/class.
As you stated front end PPF (hood, bumper, fenders, mirrors, A pillars) and ceramic coat the car for ease of washing.
This might not be what you are looking for but when I had my C7 Stingray, all I did to the exhaust was to put in an X pipe that deleted the secondary cats. That was enough for me (and my neighbours). It made it just a tad louder and deeper, a few more pops on down shifts.
