False Advertising on a car price sticker?

I went to my local Infiniti dealer and saw a g35x sedan priced for $16654. I began to talk to the sales rep about the car and I was interested in buying this car. I look at the sticker on the car and it says $16654. This was a legit price sticker including all the information about the car. The dealership says the car is then $17460 the next day. Doesn't this mean they were false advertising. I was planning on paying $16654, not $17460. The price wasn't raised due to any sales or fees they just raised the price. Shouldn't I make them let me buy the car for its original price. This isn't fair.
