I had a miserable experience the last car purchase I attempted as well. The manager wouldn't give the sales associate any pricing unless I test drove the car. Needless to say I walked out of there.

CarWoo.com saved the day for me simply because I got a price narrowed down before they even knew who I was. The only person I had to say no to after that point was the financing guy who tries to sell you tint, pin striping, and all that extra stuff. (Disclaimer: I have no affiliation with carwoo at all.)
