You could always try to do an internt search and wade through the click bait or maybe try to call GM .....Any idea on the pricing for the GS?
Or you could ask our resident Corvette Concierge @Mr.Corvette who spends countless hours sourcing such information from his wide variety of industry contacts . He is in no way compensated for this awesome information by CCF in any way incidentally. Although by way of appreciation for all his time and effort not to mention time savings for our valued membership as opposed to having to wade through who knows what kind of information from YouTube " experts" ,lol , it is possible and greatly appreciated when possible for those benefiting to make a donation. Simply look at his signature and you will see a link.
Thanks very much to all who are able to donate in what ever amount they can manage . Same goes for CCF itself as we are still, and would very much prefer to remain ad and spam free !
