If you are already getting the car with all the options installed for almost $1300 UNDER invoice, dude, i would take that money and run!
Subaru's site just appears to list the price of an accessory but it wants you to find a car in dealer inventory... So i presume those prices are not including dealer installation costs. Anyway you are already paying much less than either advertised price, even less than invoice. I recommend not pushing your luck, just my .02.
Oh here, scroll down to the 3rd forester sticker:
http://www.cars101.com/subaru_windowstickers2014.html
you can see the sticker says $192 for the luggage comp cover, but subaru site says $169.95
splash guards $147 on sticker but $109.95 on subaru site
rear bumper cover $92 on sticker vs $69.95 on the sube site.
Meh, who cares. Dealer can tell you whatever, ultimately they are making you a great offer, regardless whichever retail pricing standard is used.
Dealer might just say OK go buy all that stuff online and I will sell you the car for my invoice price. You will end up paying more plus have to do all that work yourself... hmmm no thanks!
If you are paying $1287 under total invoice for the car with all those options, the dealer is not charging you MSRP for ANYTHING. If you ask the dealer to charge you website prices for all those stuffs, you're just asking him to raise the price by something like $600. Makes no sense to do try to argue for that...
