This "$750 cash back on new 2010 Prius" and "complimentary Toyota Auto Care Premium Maintenance Plan" (from Buyatoyota.com) is due to expire Sept. 7, 2010. "Must take retail delivery from new 2010 dealer stock by 9/7/10." That's rushing it, for me. Is this deal likely to be extended past Sept. 7, or offered again fairly soon? Also, does this mean I'm limited to what a dealer has on the lot--I can't order a specific Prius? I'd like some educated opinions.
