Automakers release their April sales results next week.
Five industry analysts predict U-S sales will be down compared with April-2006.
And in a soft market that continues to shift from trucks to cars, and that means trouble for the Detroit Three; General Motors, Ford and Chrysler Group.
The analysts say there doesn't seem to be any pent-up demand for vehicles. Consumers either have too much debt or bigger mortgage payments, or are just waiting to see what happens to gasoline prices.
The Detroit Three are all in varying stages of turnarounds. All have lost billions in recent years as Japanese rivals Toyota and Honda have increased their market share.
