YES, bidding wars throw the ball in your court big time. I know a lot of folks that have done this with vehicle purchases along with other services... phone/internet/mobile internet is a popular one.And communicating with multiple dealers will ensure you get a better deal (usually). I always start a bidding war between the 2 biggest dealerships in my area. They both keep chipping at the prices until eventually they end up on a similar level and it comes down to who has the color i want. haha.
