The GM cargo net shows to still be available. the part number is 22711348. Cost on it is around $15.

 

Drorie, Thanks for the part #!! I called the parts dept. of my local Chevy dealer and talked to the same parts guy who tryed to find me a cargo net yesterday. He had searched for the net in GM Accessories and came up with nothing yesterday. Today, armed with the part #, he found it, and ordered one. He figures it should have come standard with the HHR, but for some reason it wasn't in mine...I double checked the 2 storage compartments behind the rear seats, and even looked under the spare tire, and found nothing. Thanks again Drorie!

 

LS doesn't come with cargo net

 

That explains it. Got my dealer ordered net (said "Made in Mexico" on the package) yesterday. Cost was $25.90. Fits and works great!
