Let's look at resale values a little more closely and I will try to explain how the market forces affect each and every product on the market. Some vehicles, like Volkswagen, Mercedes & Toyota for example, have excellent resale values - yet other vehicles don't hold their value as well. Why is this? Who determines the book values we all hear about? It is a mixture of SUPPLY AND DEMAND, product quality, and public perception. Supply and Demand is the primary driving force in every free market economy. It will ultimately override any 'book value guide'; government intervention, price fixing, or market manipulation. Within each manufacturers products there are further anomalies. For example, just because it is a Toyota does not necessarily mean it will have high resale value. Certain of their model ranges are not good sellers - for example the new Camry.
