From Automotive News just a few minutes ago:
"General Motors is boosting the rebates on some of its new 2007 model pickups to $2,000 from $1,000. GM tonight will give dealers details on a new round of incentives that start Tuesday, July 10, in most states.
GM said it is boosting the rebates on the light-duty versions of the Chevrolet Silverado and GMC Sierra pickups. The move comes after sales of both vehicles plummeted in June after Toyota offered huge rebates on its new Tundra pickup."
And the game continues...
