Does anyone know what the invoice price is on the base Boxster S without options? I have searched the forums and seen people who claim to have gotten "x" amount over invoice and the percentage I calculate from those posts is that MSRP is about a 16% markup over invoice. But then I also have that LeaseWizard program that is supposed to tell you invoices and it shows about a 13% markup for MSRP. Does anyone know the real number? I am going to finally take the plunge in early Feburary and obviously I would like to be as informed as possible, I need to be able to get about 10% off MSRP to get the perfectly optioned one I am looking for.

Any advice or info you guys can give would be greatly appreciated!
