You also want to try and see if they have an internet dept. you can usually get the best deals through them I am not sure how it works with Honda since as you said they are pretty popular but I know that $500 over invoice is not impossible with other car dealerships. If you really want to save money don't do any of the upsales once they have you in finance. Just buy the car and walk out the door. That is really where they make their money.
