Ask now, they have a sheet for the exact car you are looking at that will lay out all the plan (A, X, etc..), invoice, and msrp pricing.
I got my GTCS for well under X plan pricing, but YMMV. I got the wifes EB for X plan cost.
Not sure what the xplan price is on that car, but don't forget you can get that pricing and no more than $100 dealer doc fees for being a member of the MCA. I joined the MCA at the dealer during talks and got that perk. Every little bit helps.
Also traded in my 4 cyl Accord DD for my GTCS. Life's to short. I want to be able to pass that pickup doing 50 mph on a two lane, especially when they inevitably speed up while you are passing. Or that cell phone wearing BMW driver that absolutely cannot be passed because BMW.
