Thank you for your service. Get your arse home safe and enjoy those bikes.I am not sure what dealer invoice is. When I bought my 07 S2R800 in late 07 the dealer would barely budge and when it did, it was not a lot at all.
I recently just bout my two bikes at Waco Ducati (Euro Shop Waco) I actually am stilll in Iraq and the bikes are still at the dealership. I can't break it down how much I paid for each as it was one price OTD for both bikes. I can say that I think what I paid was under MSPR but not by to much.
Some places offer better deals I guess and if you find a deal that works for you then take it. We all know its worth it no matter what
