Congress is taking a hard look at Detroit's autos these days. But what about Detroit's jets?

When the chief executives of Ford and General Motors flew in to Washington yesterday to ask Congress for a $25 billion lifeline, they didn't fly coach.

General Motors CEO Rick Wagoner arrived on his company's cushy Gulfstream IV, ABC News reported. Ford CEO Alan Mulally flew in on a private company jet as well.

It costs about $20,000 to fly one of these jets round trip from Detroit to Chicago -- far more than the $900 cost of a first-class ticket on Northwest Airlines, ABC said.

Wagoner told ABC he took the private jet because he's a busy guy. Mulally declined to comment.
