After a year of ownership - my complaints are few. I had a convertible before - but needed a practical car. The HHR fits the bill to a tee! It consistently gets mileage in the 30's, with the 2.4 liter and the 5 speed manual, the car is quite responsive. I wish the car had traction control (since corrected), I hate the cup holders and the window switch location (also since fixed) All in all - this car is for an active person who doesn't want their car to look like everything else on the road.
Sunroof, leather, black chrome wheels, plastic lined cargo area, stick shift, stereo with satellite, CD, MP3 and iPod, controls on the steering wheel.
I hate the interior design. Console blows, no storage and terrible cupholders. The person who designed the stupid location of the power window switches should be fired. Unfortunately, this is the typical GM car - they ship it out the door - by the time they fix it, the public has lost interest.
