There is no comparison between the HHR and the PT Cruiser. The HHR is roomier more economical and better looking. I average 29.5mpg cruising at 75mph in hilly West Virginia. The back is large enough with the floor removed to fit a full size contra(drum corp) standing up. I love my HHR!
Excellent ride. Great gas mileage. Supurb handling. Plenty of room.
Flush door locks that don't jab into your arm. Higher armrests on the seat so I don't have to slouch.
