We bought ours a little less than a year ago, and while we were searching all of the web sites and Craigslist ads we could find from across the country, none were anywhere close to the blue book value. Also it will depend upon whether it is a basic Safari or a SE. Best advise I can give is to check as many RV classified web sites, e-bay, and Craigslist across the country to give you an idea of what people are asking. Typically Airstreams bring more than the listed Blue Book values. By the way, we love our 20" Safari SE.
