We drove 90 minutes to a dealer today that was advertising a truck that checked off most of the boxes. It was marked down $6600 off the MSRP of $78,775. When we got there, I could tell right away it had been used. Turns out the truck had 6,000 miles on it. Their first offer they came back with was at full MSRP plus their BS charges of $3900 for GPS tracker, nitrogen in tires etc. Obviously they didn't know we saw the ad. We walked out when they wouldn't budge off the advertised price of 72K. So how much off MSRP do you think a demo should go for?
