Bad dealer experience

I recently went to this dealer looking to buy a 2006 GS 300. Like any smart consumer I did my work and figured how much I should be willing to pay for this car. When I arrived at Valencia Lexus I told the salesman what I was looking to spend on their car. I also asked what I had in mine for my car. I told the salesmen to see what they could give me for my car. Well like a typical car dealership the run around began 1 hour later I was still sitting there. Then they sent the Mgr Brice (aka) closer to try to pressure me. Since that didnt work he decided to insult me. Look @ the Better Buisness Bureau and see what there about.
