I'm in the process of car shopping, as are other members of the family. At this point, there is pretty much nothing left on the lots in terms of 2013 cars, except for left-over, unwanted Darts. They're thick on the ground and the dealers can't seem to give them away. (There are still lots of trucks and SUVs, but that's more because they overstock those vehicles as they are seen as easier sales.)
As for sales figures being on target, sure they're up this year but they're nowhere near initial predictions. From the Bloomberg piece: "The Dart’s disappointing start—last January, researcher LMC Automotive had predicted sales of 100,000 cars in its first year—is a rare misstep for Chrysler".
So if the industry estimated target was 100,000 last year (by rights it should be higher this year), the company still isn't on pace to meet or exceed it. It will be close but it will still be roughly 13,000 cars short. (57,914 divided by eight to get a rough monthly average of 7,240, then adding four times that figure--28,960--to the 57,914 for a year's total of approximately 86,874).
It's also a pretty buzz-less car. I tend to work with and interact with a lot of very gung-ho car people. I've heard talk about pretty much every car out on the street except the Dart. At this point it's just flying so low under people's radar that it risks crashing into anthills.
