When looking for parts this question comes up. What is my HHR considered? I bought it used from a Volkswagen dealer, they know nothing about the car when I asked questions. I had not seen the semi panel version before, when you read any material the AA5 option is barley a mention or I just didn't notice it before. Yes, it's a 2.4L

Fits on:
06-08 Chevrolet HHR 2.2L / 2.4L
07-08 Chevrolet HHR Panel, 2.4L

 

The AA5 is an option for the Regular HHR. It was not considered its own model. So it would be the first choice.

 

^^ Like he said, (unless you're ordering a rear quarter panel, they are the same)...

 

Thank you for clearing that up.
