So Long, Toyota of Seattle

I swear, last week this lot was full of cars.  There were those multi-colored plastic pennant-things everywhere, just like a real-live car dealership.  But these guys have packed up and moved to SODO.  How do I know?  I read this sign:

They're planning on building something very large on the lot.  It will hopefully match all the other large buildings that are currently under construction in the area.  OK, so this is at 7th & Blanchard, a little outside of Belltown, in the area known as the Denny Triangle.  It sounds mysterious.  I'm thinking it needs another name.  Since Amazon is the major builder, how about the Amazon Basin?  Or how about Large Buildingville?  Anything is better than the Denny Triangle.
