I have owned my HHR for about 5 months and about 6,000 miles. The car has been fun and economical to own. The 2.2 litre engine will not win any races but it moves the car with enough acceleration to make it fun to drive. The engine is quite noisey under heavy acceleration. Rock solid on the road with plenty of room for people and things. The interior is roomy and very versatile, and I love the fold flat rear seats. Overall has been a great car.
Fun to drive and very economical
Better storage, easier to use drink holders, more quiet acceleration.
