Reviewed on May 25, 2007Although we aren't crazy about the exterior of the 2007 Chevrolet HHR, we give it credit for making a strong statement. The car is meant for cruising, not for speed, and although it has a full range of tech gear, we don't find OnStar as convenient as onboard systems.TAGS:OnStar, navigation, operator, GPS navigation, direction, GPS, radio, car, San Francisco
