A new study by driving-tests.org ranks Nissan's new Altima is the most-stolen new car on the market. The study ranks the Honda Civic the absolute favorite among car thieves. Thieves make off with more than 45-thousand Civics each year, slightly more than Honda Accords. Car thieves have different tastes in different parts of the country. Honda Accords are the most-stolen vehicles in East Coast states like New York and Massachusetts, while Ford and Chevy pickups are thieves' favorites in the South and the Midwest.
