By all means, you can post where you ordered from, sure.
As enthusiasts who always try to help each other out, let us know HOW the dealer/salesman treats you. If it's a bad experience, we WANT to hear about it. If it's a good experience, let the others know who to buy from....and you can put something up in the Texas area forums letting other Houston folks know that "so and so" did you right.
We have a thread in the San Antonio section talking about dealers and where to go. We have EXCELLENT feedback and found two GREAT dealers in SA that go MSRP. So, help them out!
(but don't go putting it in every thread all over the board....that gets annoying...lol)
