pricing question on 2010 roadster.

[tazz01]

I know there is several posts in here on pricing but just a general question on what price should I try to get.

Been talking to a dealship by Vancouver for a 2010 carbon silver roadster A7, so far they are including the lite door plates, removal of headlights/shipping and reinstall for the headlight mod, and clear bar on all the major pieces....I just don't feel right on still paying sticker price (yes I am kind of cheap but money is money ) but with them throwing in all the above not sure how much I should try to get off sticker now is about ~55k nav/auto/sport package...Just wanted some idea's what everyone thinks would be a good deal....
