I'm looking at a 2011 Silverado quad cab truck. It was a dealer demo and has 4800 miles on it. My question is, what should I be reasonably asking them to knock off of the price for the 4800 miles THEY put on that truck? I have to take it back in about 5 hours so any input on this before I leave would be appreciated! I know as soon as I drive off in it the value drops drastically so I think that what they put on it should count for something.
