General Motors Corp. and Mitsubishi Motors Corp. are both planning to add extra incentives to clear out 2005-model vehicles.
GM will layer additional discounts on its employee-pricing offer before it expires next week, four GM dealers said Wednesday.
GM will launch a "96-hour countdown" sale on Monday with $1,000 discounts on top of the employee incentives, which let customers pay the same price GM employees pay, dealers said.
Mitsubishi will provide U.S. customers with free gasoline for a year to help clear out 2005-model cars and trucks and halt a 30 percent sales decline.
Buyers of models including Galant sedans, Eclipse Spyder sports cars and Montero Endeavor SUVs will receive gasoline debit cards for between $1,500 and $2,500. The offer runs from Friday through October.
The Japanese company sold 87,074 vehicles in the United States this year through August, down from 123,715 a year earlier.
