I have a number of ship models. A lot depends on the amount of detail, quality of paint job and the execution of the build. There is much variability out there. Is the model actually metal? Does it have lights? If well done, $450 is not bad for such a large model, particularly if metal and detailed (port lites, cleats, bollards, cargo cranes, running lights, anchors, etc.) Do you know the beam (width); will it fit for you in that dimension?
Do the cargo hatches open? If so you could have a crane on the dock loading it. You could also build a tug to go next to it.
Arthur makes a good point about scale. I had the Lionel tug and though correctly scaled it looked really awkward on the layout. If you have a chance consider getting more measurements such as beam and height to mock it up on the layout in cardboard.
I have a 6' long sailing schooner (not a waterline) and it is a commanding presence in a room. Such large models are not real common. This could be a great opportunity to get unique piece.
