I beg to differ.
This came as an order option with the car ($425 on the invoice) and the Flag on the cover are not C6 it is C7.
Not sure where you got your info, but this is a Genuine Factory GM C7 Stormproof Cover.
The Part Number of the actual cover is 23142884.
It looks like the factory put the users guide for the C6 Cover in the new cover.
Not sure why this is, lazy I guess.
Sorry for all the confusion on the part number. I Guarantee It!!!!!!!
I did notice the flags were c7 but part number didn't agree. Based on the new part number you provided it would be a c7.
What is the inside of this cover like? I don't need an exterior cover because the car is kept inside. I just like to look of this one.
