The good times keep rolling for carmakers, with analysts reporting Tuesday that the auto industry will surpass estimates for September. Sales look set to jump about 13 percent overall since last year, and could reach 14.9 million vehicles, which would be the industry’s highest level since 2008. Toyota recorded the largest increase, selling more than 170,000 vehicles for a 41 percent jump. Volkswagen Group of America had its best September since 1972 and recorded a 34 percent increase. Ford still disappointed, selling about 200 less vehicles than this time last year. Experts attribute the industry’s overall growth to cheap financing and strong recent performances from foreign automakers.
