Actually, Tribeca sales have been over 2000 per month for the last three months, increasing slowly each month. Dec. figures are not in yet. Subaru is happy with Tribeca sales especially since gas prices slammed the SUV market hard. Subaru also lost sales because they could not meed demand on certain configurations, which are now available...such as 5 Pass with Nav.
However, many of these sales may be to loyal previous Subaru owners, so it remains to be seen if the Tribeca will continue to sell well. My feeling is that Subaru will add more power, tweak some features and cosmetics and probably succeed with it. They need an SUV in their lineup as well as a minivan.
In the mean time it's nice to own a car that I don't see every two minutes. There are WRX, Outbacks, Sports and even an SVX on my block...nice to have a car that's "new" and still getting compliments from the ladies!
