6 months ago, I had good success in bargaining down my 'dealer of choice' (the closest one) by getting on-line quotes from 5 other dealers in the area, then sending them to the dealer I finally bought from; beat the MSRP by a bit, with no hassles (but I got suckered into the wheel locks! Rookie error). In the process, I contacted a couple of the dealers online directly, but I also got multiple quotes from area dealers via the link at Cars.com. At the advice of a friend, I also got quotes via the online broker Carsdirect.com (which also can link quotes from area dealers). The Carsdirect.com quote wasn't quite as good as some of the more competitive bids but still beat the MSRP.

Of course, that was 6 months ago, and times have changed. I was also apparently lucky to have so many dealers within 'striking distance'. But my friend's experience with Carsdirect.com was very positive (though she bought an evil Toyota)-- she had to wait ~7-10 days for delivery, but then had no problems with the car, delivery, or financing. Picked up the car at a her local dealer, where she has warranty service performed (again with no problems). If I hadn't gotten a better price from the dealer, I would have gone this route, but obviously I can't speak from personal experience.

Nevertheless, If your local dealer is giving you such a hard time, I wonder if this might be an option to explore?
