the dealership I got my z51 from has a 5k (A.D.M)mark up on it. After telling my salesman I wouldn't pay a penny over sticker he put me on the phone w his manager, I almost cursed him out..(rude). finally he said come down and when we were almost finished w the paper work, those SOB hid the 5k price in the sales contract that's when I told them to pi$$ off and they came and chased and said.."ok we are sorry. its almost unreal but if you don't want to have to wait till feb. you got to negotiate but well worth the hassle....
unfortunately, the longer these are on 'constraint, the more we are going to see these ADM fees.....
