We bought our new '15 Odyssey van via Costco Auto Sales at this dealership and I am SO THANKFUL that we did it this way - set price, zero haggling, literally no stress or pressure.
The way the costco pricing works is that its a pre-negotiated price per model level. We knew what we wanted as far as model and costco gave us a contact at the dealer that went by the costco-negotiated price. He finalized features and colors we were interested over email as well as the out the door price (we were paying cash),we went in the next evening, test drove it, looked it over and because we both like to sleep on it before making a big decision/purchase, we didn't buy until the next day. The longest process when we purchased was probably the back and forth emails to find the ones with the features and colors we wanted. Everything else was EASY AS CAKE and painless. Even paying cash you have to go thru the finance people but even that was easy and quick and the people were not pushy even for the extras (warranties, lojack,etc).
I also think it's a Honda of Tempe culture because I've gone back for routine maint or extras like custom seat covers and odyssey floor mats and you don't observe pushy tactics from any side... it's really why I'll continue to take my business there.
