The new cars that sit on a lot do not all sell. There has to be a place for them somewhere. They do not all end up on used car lots. Think about it. So many cars made every year, and they go where? Does anyone know?
When the new models come out, the prices go down on the old ones until they are sold. These are the cars I usually buy: one year old, very few (demo) miles, never titled, brand-new warranty, and at least 20% off sticker price. Many other people also shop this same niche in the market every time they need a new car.
