My boss spoke to a nissan dealer last week re the 1% deal. Was told if he had cash or pre-approved finance he could have $7000 off the price but not with the 1%. He worked out that he is no better off with the 1% deal and the extra $7000 on the purchase price than if he just went and got finance himself. He was also told that he had to pay it off in 3 years so maybe worth asking some questions when you next speak to them.
