Reported the ad as a scam.
They haven't even started production on the C7 yet and with the 1,400 car hold back in the shipping lot, I don't think they'll be doing any deliveries until late August/early Sept. Plus, I might be wrong but I think the Convertible isn't available until 2015.
Doesn't really matter though because however you slice it, pretty much everything they wrote in the ad is wrong.
