I found this post from The Car Blog to be pretty informative:

In my daily investigative online reading, I came across a story that almost seems too far-fetched to be true. Dealers across the country are literally selling out of a vehicle model. Certainly, this would be rare for any domestic automaker, except for brand-new, just-introduced models. What made the story even more remarkable, is that the vehicles that are flying off dealer lots faster than the factory can produce them is not an exotic sports car or headline-grabbing retro revival.
