2012 Prius Three in Blizzard Pearl w/option - Price Evaluation

Hi Everyone - I received the latest price quote for a 2012 Prius Three in Blizzard Pearl with the following options - clear paint protection (which includes door cups, door edge guards, rear bumper protector), carpet mats, and Toyoguard Plus. Total MSRP = $28,321.00. I've gotten the price down to $23,411.00 w/o TTL. This is in the Southeast (NC), and I'm less than thrilled that their doc fees alone are $499! I'm wondering if I should bother bringing it down more to $23K given that it's year-end and that I'm paying w/o financing.

 

I'll clarify that the original offer price (not sticker) was $23,995, which was their Internet price. I think what they're offering now offsets the ~$500 doc fee, plus it is below invoice. I think the invoice is (based on my research on edmunds.com and other websites) is $23,799. Just wondering if its worth to try to bring it down more to $23K, and if offering to pay w/o any financing bears any weight, or if I'm just going to price myself out of the market.
