Depends on your dealership. Sometimes they'll sell at MSRP but most won't because they wan't the extra profit. Hopefully it won't be the case with the Cruze SS but it never hurts to become friendly with your chevy dealership sales guys.
Unlike the Chevy SS this is a product I can see having much more demand and it's a hatchback so it targets a lot of key areas in serving someone. They're just going to be better off monitoring how things go and to go with what the market wants.
