Choices are somewhat limited on 2012's, you can't order one anymore, so you are stuck with what they have on the lot or what they can find at another dealer.
Base + Sport package with typical options invoices for about $34K. If you don't have a trade-in you should be able to get one for invoice if you hardball, but remember, you may not find too many PW base + sports to play with. Unfortunately when the "new model" comes in and no one wants the old you have a great shot at a killer deal but it does seem like there are a few people wanting to grab a '12 while they can, so you best get moving before the dealers get wise.
