Kelley Blue Book's new car shopping website kbb.com has named the most researched vehicles of the first half of 2005. The usual suspects occupy the top slots (Accord, Civic and Camry), while the hottest new comer has got to be the Ford Mustang, which rocketed to the number four spot. The website is even reporting that the new Mustang's popularity has improved the resale price of a 2003 or 2004 by $500 to $1,000. Other notable vehicles on the list include the Mazda3 at 16 and the Chrysler 300 at 18. The list is compiled according to the number of pricing reports requested for each make and model of vehicle.
