Just passed 3.5 weeks with no prospects.
I know what's going to happen: I'll gradually get away from my routine of checking the ads several times per day, and just when I stray, someone local will post a killer deal that'll get snapped up before I even know about it.
If there's nothing on the Prius front by mid-August, I'm going to cast a wider net and start considering any reasonably efficient manual transmission car for the next winter beater.
