Kelley Blue Book, a resource for used and new automotive information, generated more than 28 million consumer pricing requests on its Web site kbb.com in September. Based on pricing reports generated, Mercedes had several of their luxury models unexpectedly making the September list. With the phenomenon of zero percent financing, no interest ever, and some of the best deals in decades, many consumers are finding their way into luxury vehicles. "The amount of money it once took to buy a Chrysler Sebring or 300m, can now buy a Mercedes C-class," said Charlie Vogelheim, executive editor of Kelley Blue Book. "The current economic conditions and dealer incentives allowed companies like Mercedes and BMW to sell into new markets and have a huge presence on our top 50 list for September." Another 'Top 50 Most Researched' car was the 2003 Nissan 350Z. September's top five are the same as the last several months, but in a different order. Chevy/GMC Silverado and Sierra trucks again top the 'Kelley Blue Book Top 50 Most Researched' list at No. 1. Honda still holds two coveted spots in the top five with the Accord and Civic. Rated one of America's best-selling vehicles, the Toyota Camry holds strong to number five this month. SUVs remained strong in September with Ford's Explorer, Expedition and compact model, Escape.
