Did your purchase include a trade or incentives?
It would be great for others trying to negotiate on same model, if you could post the sale doc, showing the model and dealership info.
Hey, do you mind telling me which dealership you bought your car from for $23k? I'm up in Maine and looking to buy a 2016 Civic Touring. If they're willing to sell them for that price I may as well drive down to Mass to grab it!
