General Motors is again allowing salaried staff and retirees to offer cars to non-employees at employee discount.

The 130,000 white-collar workers and retirees can offer the discounts to up to two people each under a deal running until 5 January, Dow Jones said. It has previously offered a similar deal but each worker could only offer the discount to one buyer.

The automaker is currently running its annual year-end 'Red Tag' sale that offers range-wide incentives.

"The price you see is the price you pay," an advertisement currently being run by southern California Chevrolet dealers tells website and TV viewers.

Us automakers have recently run 'employee discount for everyone' incentive schemes in an effort to prop up flagging sales.
