General Motors’ Chevrolet brand is on target to reach sales numbers it hasn't seen in a quarter century, the division's new general manager, Brent Dewar, told the US website The Car Connection (TCC). "Our goal is to try to get back to three million," [a level Chevy last touched in 1979], Dewar reportedly told TCC at a Nashville, Tennessee celebration marking the Corvette sportscar’s 50th anniversary at the weekend.
