I submitted an order today for a '15 WRX Limited. I called every dealer in my area (Roberts Auto Mall, Rafferty Subaru, Colonial Subaru, Concordville Subaru, Matt Slap Subaru, Delaware Subaru, Glanzmann Subaru) and none of them were willing to negotiate a deal less than MSRP so I went with the dealer that offered a lifetime power-train warranty.
Did I overpay? I asked if there was any room for negotiation but they all gave me the same response. They also confirmed that the Subaru VIP Program, BJ's, & Costco were all illegible for the WRX/STi
