Honda and Toyota cars are the most researched online, writes Internet Retailer, citing a study from Kelley Blue Book, according to which Toyota captured seven spots in the top 20 and Honda took five slots - all in the Top 10. Only two domestic vehicles made the most-researched list: the Chevrolet Tahoe and Ford Mustang. In the top 5, Honda Civic and Accord are the most researched vehicles, followed by the Toyota Camry, Corolla and RAV 4.

According to KBB.com, rounding out the top 10 were Honda's Pilot, Odyssey and CR-V; Toyota's Highlander; and the Chevrolet Tahoe. During the first half of the year, two vehicles fell from last year's list, the Chrysler 300 and Jeep Grand Cherokee, which were replaced with two vehicles making their debut in the top 10: the Toyota Rav4 and the redesigned Chevrolet Tahoe.
