2500 units is fairly
2500 units is fairly meaningless with respect to any other model of car made. There were approximately 282,000 mid sized cars sold in August 2012. volt will be 1% of that figure. If you remove the $18M in government funding this number would be significantly lower.
And in fact the plant shutdown does indicate that volt sales are no reason to keep the plant running and there is more than enough inventory to meet this very, very lackluster demand.
Keep the glowing headlines coming - the choir wants more good news.
