With all due respect most of you think you know what "invoice" is and few of you actually do. I'm quite fed up with this boasting. Due to the vagueness of this method and the ambiguity of actual "invoice" or dealer cost I propose a more accurate and transparent method where everyone can make apples to apples comparisons;
1 calculate the exact MSRP of YOUR model as equipped and report to forum.
2 report to the forum the exact $$$ discount and calculate the resultant percentage discount.
This method is crystal clear without the nonsensical B.S. about "invoice". I'm quite sure no dealer will lose money for you. If you can't follow the above simple method don't waste time posting about your "great deal".
