I heard stories of fire-sales of GTO's on the east coast for under invoice, or something close to it...

Well, I just cruised over to the local Pontiac dealer over here. And they are still marked at MSRP + $3500, which is better than the MSRP + $10,000 they were earlier this year, but still...

Usually, these dealers here offer Costco members $500 over invoice. But MSRP + $3500 IS their Costco Member price.
