after making a deal on monday, im waiting for the dealer to get back to me on the delivery of my NHB EX. they give a call today and say that these models in 5spd are hard to find in nighthawk black around my area however they did locate one further and said that by the time it arrives here, it will have 400-500 miles put on it. they are offering me this additional mileage at a discount. how much is 500-600 miles worth in dollars depreciation of a new civic? anybody have an idea at what i can get for this?
