All sales folks will negotiate. ALL OF THEM! It's part of sales. My wife (the best sales person I've ever seen) taught me:
1. You (the buyer) must demonstrate you're serious. Tire kickers do not get the "best price".
2. You are trying to determine their (the seller) walk away price, the price at which they will walk away from the deal. Start low enough and work up.
3. They are trying to determine your walk away price. If you don't walk away at least once, you don't get their best price.
My dealer allowed large (50%) discounts on the extended warranty, no charges for dealer freight or prep, and discounted installed options. Yet the sales contract showed MSRP. The whole time I had $8,000 cash laid on the sales manager's table. He knew I was serious.
So be brave and negotiate. Remember to walk away at least once!
