Speculation here, since these days different cars roll off the same assembly line the costs of keeping a lower-volume selling model aren't as great as they once were, so slow sales alone might not kill it. They can certainly choose how much they want to spend on advertising and marketing at any point. But if other issues come up, like updates are needed to meet new regulations, some supplier contract ends, or if they're getting a bunch of lemon law complaints or warranty issues that force them to throw more money down the drain, yeah, I bet they'll take a much harder look at the program.
