A floor model is a floor model. If it's out of the box and people have used it, no matter the number of hours, it is a floor model. New in box means no one has used it.
I bought my machine as a floor model and the dealer gave me a great discount plus threw in a package of bobbins, another foot, and threw in a double cone holder that attaches to the machine. I actually went to a dealer that was an 1 1/2 hour away and in a different state.
Either bargain harder with the one closer or go to the farther one, because $1600 is a lot of fabric, notions, etc., especially a better deal if he gives you a new in box for less money.
