General Motors will cut base prices on 85 to 90 percent of its 2006 Chevrolet, Buick, Pontiac and Saturn models, according to an Automotive News report on June 20. Cadillac's initial 2006 prices will increase marginally. GM has not released prices for Hummer, GMC and Saab. The 2006 Chevrolet Impala LS will start at $20,670, a reduction of $1,680 not including shipping. The Impala LS will get side airbags and power seats as standard equipment. A variety of other vehicles will also get features such as power seats, antilock brakes, stability control and OnStar as standard equipment. Those features were previously offered only as options. Prices on highline vehicles such as the Corvette, HHR and Cadillac XLR coupe and Hummer H3 won’t change. The moves are part of GM's strategy to wean buyers from hefty incentives and lure Internet shoppers by advertising lower prices, according to the Automotive News report. GM plans to shrink dealer discounts by 1 percentage point, yet will raise discounts on options and accessories by as much as 8 percentage points, the report said.
