I have been to 3 dealers in the last week that had marked up from MSRP at least 2k.
But when you tell them you're not paying over invoice, their tune changes.
Any dealer that won't give you a car for invoice or within about $300 over it, find another dealer. There are tons of dealers who will do it.
The big mystery in new cars is how much the dealer pays for the car from the manufacturer.
IT IS NOT INVOICE!!!
Usually it is less, depending on the size of the dealership.

Anybody looking for a Xfire, tell them you'll only pay invoice, even if there is dealer markup.
