A recent search for new Chevy Volts on cars.com unearthed 9,254 vehicles currently at dealerships for sale. There were another 258 late-model, used Volts available. About half of those had less than 5,000 miles on them. Considering the abysmal sales rate for the self-proclaimed electric wonder-car (1,306 in April for those keeping track), the unofficial inventory numbers point to about a seven month supply of Volts available. Ideal inventory levels are considered to be in the two month range. It may be near time for General Motors to halt production, yet again, for the floundering Volt.
