Values on vehicles larger than a 1-ton vehicle, or one equipped with special on-board equipment, vary widely in value. While age and mileage are indicators of value, frequently the type and condition of the upfit becomes the primary reason for establishing a vehicle's overall value. Determining commercial vehicle value is very problematic and requires the consumer to compare prices from a range of sources (e.g. trade journals, equipment magazines, postings on the internet, summaries of auction values) to get the best determination of the vehicle's overall potential value. Keep in mind, rarely do two similar commercial vehicles have the same upfits, mileage and condition to compare value. However, comparing similar vehicles can give you a range of values as an indicator of the potential value of your trade in vehicle.
