For those of us lucky enough to have ordered our Prius before Mar. 15 when the MSRP base price was increased by $300, a $300 rebate from Toyota should be forthcoming as per a letter sent from Toyota. This rebate is supposed to come from Toyota, not the dealer. I purchased my Prius on Apr. 8 and took delivery on Apr. 16 and, so far, after 6+ weeks, no rebate check. Anyone else received theirs and, if so, how long did it take to receive it? Anyone else still waiting?
