I found one that's identical except for the rubber mats. Assuming you're still paying for the 20" wheels....
MSRP $37,045
X plan (after $2750 rebates) $32,014
As bbf2530 pointed out, without X plan you'll be paying at least $300-$400 in documentation fees and potentially other fees as well. With X plan you'll only pay $75. Tax, tag and title are the same.
X plan is not only cheaper, but safer since the dealer isn't allowed to hide any fees or pull any tricks, keep rebates, etc.
