DETROIT – Analysts expect U.S. light-vehicle sales to climb to a seasonally adjusted annual rate of 17 million in April, Reuters reports. Higher tax refunds and lower home mortgage rates pushed new car and truck sales up 3 percent to 5 percent in April, analysts said. April and May are already high-volume months as consumers use tax refunds on down payment of cars. Last year’s adjusted rate in April was 16.4 million. Toyota Motor Corp. and Nissan Motor Corp. are expected to lead the industry with stronger sales, Reuters reports. Automakers’ April sales reports will be issued on Monday.
