MSRP vs. MAS

Well just got offered MSRP from a hometown dealer. My dilemma is that I'm currently overseas and have the opportunity to purchase through Military Auto Source. I want to hold of as long as possible since MAS still hasn't been able to order or even price one out yet. I am fairly certain that they would be at least MSRP if not closer to invoice. I know that the longer I wait though the bigger the chance is that I miss out back home and potentially find out that MAS wasn't worth my time in the end. Just trying to get some feed back or maybe some input (which I have done research on the forums) on MAS. I just would hate to see them drop it as a lottery vehicle like they did they GT350 over here. Thanks in advance.
