The Automotive News price analysis includes 1,560 of the 1,590 cars and light trucks on sale in the United States.
Excluded are a few exotic sports cars and ultraluxury sedans whose sales are low and whose price swings do not reflect the overall market. Those brands are Aston Martin, Lotus, Ferrari, Maserati, Lamborghini, Rolls-Royce, Bentley and Maybach.
The analysis covers 99.6 percent of the 16.9 million cars and light trucks sold in the United States last year.
The study compares current sticker prices with those in effect in May 2004. Every number in the study is sales-weighted. That means that every price is accorded the value represented by its market share.
For example, the Chevrolet Impala last year accounted for 10.6 percent of Chevrolet sales, 6.2 percent of General Motors domestic sales, 2.9 percent of Big 3 sales and 1.7 percent of industry sales.
The Impala sticker price increase for the 2005 model year is $953. That figure was applied to each of the four market shares to determine the impact of the Impala increase on each segment.
Major items of optional equipment that were made standard are not considered price increases. If a major item was deleted, it is considered a price hike.
