I needed a vehicle that was mainly a commuter car, but also had to have good utility for hauling my bikes on the weekends. Also, it had to be comfortable & roomy enough to take 2 adults and 2 large dogs on a cross-country roadtrip when needed. The HHR fit the bill perfectly. Tons of cargo room, especially with the seats folded flat. I love this car, & my wife does too.
The passenger seat folds flat so you can fit that really long cargo in. Need to pick up some drain pipe and 2x4's at the Hardware store? No problem. Also, the 2.2L engine is great. Silky smooth, lots of pep, and power to spare. For this segment of vehicles, it can't be beat.
I would like to see the door locks moved. When I rest my arms on the door, they can get in the way sometimes. Other than that, no real complaints!
