I think they are somewhat limited every where really, just not that common of a car. I have a 2.5 SE and I have seen one other JSW in my area, a TDI.
Between two VW dealers here, they have 7 JSWs. One dealer has 5 of them, and they are the biggest import dealer in the area (Dorschel in Rochester, NY). And that is all models combined (TDI, 2.5). If you want something more specific, the inventory narrows even more.
