This is a superb example of pushing short-term income at the expense of long-term fiscal sustainability. I suspect sales are down or the manager or distributor is offering some sort of "spiff" on certain models. I don't blame you for being turned off by the experience.

Having said that, I also note that buying leftovers during a model change/update is often a good consumer strategy -- that's how the first owner got my Bianchi, and that's how I bought the 2001 VW Passat wagon, right before the 2001.5 facelift. (I can live without the vastly improved cupholders and the added chrome bling.)
