Prius "hottest" car in Sept 2007

This comes from LeftLaneNews, my bible for all things automotive (/sarcasm), where they report the Buick Enclave is the hottest model of September, but in the middle of the text they report "Tied for first with the Toyota Prius, the Enclave averaged the fewest days on a dealer lot before being sold. " So apparently that makes the Enclave and the Prius the hottest cars for Sept. (I think the # of days on the dealer lot is about 10, about double what the Prius was back in its months-long waiting list heyday, but obviously still quite good, particularly for a 4-yr-old model). I'm wondering if they're reporting it now because this is the first time the Prius wasn't on the top of the list by itself? That's just speculation on my part however.

This was based on a report from the Wall Street Journal, maybe someone with a WSJ account can see if it was better reported there?
