What is my van worth?

Go to Bluebook.com. web site. They will ask a series of questions about your vehicle such as mileage, ever smoked in, any damage, etc. and at the end of this short questionaire it will give you an estimate on value. Also check with your local bank or credit union. They usually have a pretty good idea of value because they make loans on vehicles.

also, if like you say it has many valuable extras, then what it is worth and what someone will pay might be two different things.
