Wondering if you guys can help. I'm looking at a Black 2010 Accord Coupe EX-L (no navi, not V-6) listed for $27,500. I can't seem to find the invoice price on the net and haven't asked the dealer. Wondering what you guys think with regards to negotiating price. How much would you pay?

 

I would start by looking at Autotrader.com and looking for comparable models nearby. Find the cheapest one listed on autotrader and negotiating based on that should be easy (since you could simply go to the lister of the cheaper car and buy it from them.)
Or go to nearby Honda dealer websites and do the same thing.
