waslk out at least twice... let them know you are ready to walk away from the deal, and they will give you rock bottom.

Usually people don't have the balls to do it... but about 4 years ago I bought a fully loaded Mustang GT and walked out twice. ended up getting for $5,600 less than the sticker price.

Were the Oakley blades included in that price?
