Black Book is working with a vehicle upfitter to put a number on the value of its modified products.

The provider of automotive pricing and analytical services is integrating with Fox Factory Vehicles, an upfitter/modifier of performance trucks, cars, vans and SUVs for Ford, Chevrolet, GMC, RAM, Jeep and Mercedes Benz, to enable dealerships, lenders and insurance companies to quantify the value of Fox Factory’s modified vehicles.

Fox Factory Vehicles will give Black Book detailed package content and cost data and Black Book will ensure each vehicle is decoded and valued down to the VIN level, which the companies said is a first for upfitted vehicles. The integration is designed to eliminate the guesswork of treating packages as simple add or deduct classifications and provide a “true reflection” of the vehicle’s market value.

“This partnership creates a new level of confidence and precision for dealerships, lenders and insurers who work with Fox Factory Vehicles,” Black Book president Jared Kalfus said. “By combining Fox Factory’s package data with our trusted valuation methodology, we are providing a unique advantage in capturing and accounting for the true value of vehicles they are buying, selling and lending against.”

In a news release, Fox Factory said its vehicles maintain factory warranties and comply with all regulatory requirements from the National Highway Traffic Safety Administration and Federal Motor Vehicle Safety Standards, but the vehicles it delivers through its nationwide network of more than 2,000 dealers, featuring unique proprietary packages from the Black Widow, Rocky Ridge, Harley-Davidson, RTR, Black Ops, Outside Van, Fox Factory Truck and AGwagon brands, have posed valuation challenges for the industry.

“Integrating our comprehensive package information with Black Book ensures our vehicles’ residual value is accurately represented in the marketplace when our customers choose to trade them in to a dealership or sell them outright,” Fox Factory vice president of performance and strategic relationships Scott Vickery said. “That benefits everyone within the transaction cycle, from our loyal customers to our valued licensed partners to our OEM partners and their franchise dealers, and finally to the banks and lenders we all collectively work so closely with.”
