Even before the war in Iraq started March 19, the no-interest loan offers that once made auto sales sizzle were starting to fizzle, according to the Detroit Free Press. Now that another crisis threatens to keep potential car buyers out of showrooms, what kind of bargains will automakers trot out next?

For the rest of this month, probably nothing more than the current, historically generous incentives, automakers say. But after that, incentives could go even higher, some experts say, the Free Press reported.

After the terrorist attacks of Sept. 11, 2001 -- which partially inspired the current war with Iraq -- the U.S. economy was helped back onto its feet by zero percent car nloan offers, first by General Motors Corp., then Ford Motor Co. and the Chrysler Group. Those offers are still around, but they are losing their pop, the Free Press said.
