A quote from the article above
Other older vehicles, like the Chrysler PT Cruiser (sales down 42%), are losers because they grew old and were never updated. Models like the competing Honda Element and Scion xB caught the eye of buyers looking for something new and trendy. Element sales are off this year, but only by half as much as the PT Cruiser's. The Scion xB's sales are up 8%.This is one example of an automaker that has learned at what point to cut its losses: Chrysler announced January that it stopped building PT Cruisers last December.
