We have always purchased new cars. We are still making payments on our 2007 truck. My 1999 van has 237,000 miles on it and my commute is over 100 per day. We are seriously considering a used vehicle - a compact SUV or another minivan. In our area, new car dealers will typically come down 20% from the sticker price. How much can I expect a dealership to come down on the sticker price of a used vehicle?
