NEW YORK (AP) — General Motors Corp. says it is offering employee pricing to everyone on nearly all 2008 and some 2009 vehicles.

The Detroit automaker says the deal includes all 2008 vehicles except medium-duty trucks. Eligible 2009 vehicles are the Chevrolet Cobalt and HHR, the Pontiac Vibe and G5 and the Cadillac CTS.

GM says the promotion will run from Aug. 20 through Sept. 2.

Employee discounts generally are 10 percent below the invoice price but vary by model. GM in the past has used incentives across most of its model lineup to clear out inventory to make way for new models.

The 2009 models will make their way to showrooms in late summer and early fall.

GM shares fell 31 cents, or 3 percent, to $10.05 in morning trading.
