I purchased the 2008 HHR Special Edition (which is kind of like the 1LT trim level with some extra slick cosmetics). I get compliments on this car everywhere I go. I have used the storage capabilities of this vehicle countless times. Both the rear seat and the front passenger seats fold down, with extra storage in the "trunk" floor. Quiet ride, great stereo system with the 7" sub in the back. Mechanically, this HHR has performed flawlessly. Not a single problem. Due to the extended rear end of the HHR, there is a blind spot in back that makes merging lanes a bit tougher. Nothing terrible, but check twice before you make your move. Love the HHR!
Looks, ride, storage, MPG. Best car I've owned in years.
They have fixed this in newer models, but the cup holders are placed annoyingly under the armrests. Addition of electronic blind-zone alerts in the mirrors.
