Part of why Subaru has never become a mainstream brand is the lack of attention to detail. Folks like me that want the best AWD and decent economy in a wagon package don't have a lot to chose from, so Subaru is often "it."
The 1996 OBW was brilliant. The 2000 OBW was a better product even if it wasn't the ground breaking idea the 1996 was (kudos to the Eagle, but poor execution). By 2005, it seemed Subaru was on a real roll. The 05 Legacy and OBW were sleek and the AWD system was not only preserved, but improved. The Forester was old, but hanging in there. The WRX had a following and the STi was hailed as the king of it's crazed segment.
Then the world got fat, and it seems Subaru has decided to as well. If the 2010 Legacy and OBW are signs of things to come, the Impreza and Forester are next to be super-sized and cobbled together.
