I ordered a cargo liner off of autopartswarehouse.com. If you look at the picture on their site quickly, it appears that the liner extends to the back of the front seats.

Here's an actual photo of the item. As you can see, it looks quite different.

I thought I'd post this in case someone else was thinking of getting one.

 

My company sells these and they do not go to the front seats. I do not know of any that do.

I went with the NPI rear capeted cargo tray. It matches my SS interior carpet and my front floor liners perfect.

The best floor liner and cargo liners we offer are the NPI made by Lund. I have had them in 3 vehicles now and just love them and they all have worn so well and been easy to clean. It is like the regular carpet but it protects your carpet.

Sadly thiers only covers the rear area too.

 

That pic is not an HHR and whatever it is looks to me like the back seats are up.

 

I got the rubberized liners that fit the panel versions of the HHR....

Works great.
