Filed under: Toyota , Earnings/Financials Toyota saw another unfortunate month of sales in September. The automaker saw its sales figures fall by 18 percent compared to the same time last year, thanks largely to lower-than-average dealer inventory brought on by this year’s earthquake and tsunami disasters. Toyota sold 121,451 vehicles in the U.S. last month across its three brands. The company moved 147,162 vehicles during the month of September last year. Even so, the automaker says that October will show sales improvements, according to Automotive News . Bob Carter , group vice president of Toyota Motor Sales, said that right now, U.S. dealers have a 30-day supply of vehicles, and that inventory will continue to grow in the coming months. Carter also underscored the fact that his company would reverse a five-month trend of sales losses in October and once again post gains. That’s likely to be true given that the 2012 Toyota Camry and Camry Hybrid are likely to bring in buyers as well as the company’s Prius V .
