REDWOOD CITY, Calif. -

Two more brands now are included within the Certified Pre-Owned Center of Dealix’s flagship site for dealers.

Now integrated are CPO units from Nissan and Infiniti. Dealix executives noted Nissan and Infiniti are the eighth and ninth manufacturers in the past year to bring their CPO inventory to UsedCars.com. During that period, they mentioned the site has seen its CPO inventory increase by more than 47,000 units.

As inventory has expanded, Dealix determined the number of visitors to UsedCars.com who are searching for CPO units has grown as well. The company indicated 14 million queries for certified vehicles have taken place at its site so far this year.

To handle that load, Dealix reiterated features unique to its Certified Pre-Owned Center:

—A special section highlighting program details for all of the manufacturer programs featured on the site.

—Tools to help visitors research and compare certified pre-owned programs.

—The ability to initiate CPO-only searches by brand, as well as ability to filter searches to focus only on CPO vehicles.

—Special badging on every CPO vehicle in the site’s inventory, making it easy for buyers to discover these vehicles when conducting a search.

Dealix believes blending the Nissan and Infiniti programs into the CPO inventory is crucial because the brands have a comprehensive, 156-point certified inspection that goes with a six-year/100,000 mile warranty.

“The Nissan and Infiniti CPO limited warranty programs will be important additions because of the added value they provide to consumers through extended coverage up to 100,000 miles, title insurance and trip interruption assistance,” Dealix contends.

“To receive this coverage all Nissan and Infiniti vehicles must pass one of the most rigorous and comprehensive inspections in the industry,” the company added.

Having nine automakers contained within the Certified Pre-Owned Center is a way Dealix thinks it’s responding to market demand. Executives cited the 2009 Used Vehicle Market Report from J.D. Power and Associates that revealed more than 60 percent of used-vehicle buyers are beginning the process with the goal of purchasing a CPO unit.

“Our goal in launching the CPO Center was to make sure that we were meeting consumer demand for CPO vehicles — and providing them with choice by featuring a wide range of manufacturer CPO programs,” emphasized Egon Smola, vice president of Dealix’s new and used car leads businesses.

“We’re excited to have the Nissan and Infiniti programs included on the site,” Smola added.
