"Desperate Housewives" actress Eva Longoria was on hand Sunday to help Chrysler Group executives show off their latest concept cars, including a sleek sedan with a sumptuous interior based on the popular 300C.

She sauntered across the stage as DaimlerChrysler AG Chief Executive Officer Dieter Zetsche and Tom LaSorda, who replaced Zetsche as president and CEO of Chrysler, warmed up the crowd of journalists.

And she rolled up with LaSorda as they brought the Imperial concept, which sported the look of a highly refined 300C, on stage for a second showing.

"I'm desperate for one of these cars," she quipped.

Chrysler also showed its Dodge Challenger concept, which was inspired by the 1970 version but updated with a 6.1-liter, 425-horsepower Hemi engine.

Chrysler hasn't said whether either concept will reach the market.
