Here's my 2¢ from a woman's perspective ~ price the exact same setup at another dealer. If your suspicions are true and you find the exact same setup significantly lower, get it in writing. Now, without the girlfriend knowing, load up your birthday gifts and head out to the original dealer. Get the full refund and then show them the reason why for the return. Even if they match the other dealer, I still wouldn't do business with them.
Next stop, the other dealer. Load up and head on home. Plan a really nice evening just for her and then explain what you did and hand her the savings.
