2011 Buick Regal CXL Carbon Black Metallic. 6-Speed Automatic Electronic with Overdrive. Don't let the miles fool you! Real Winner! This 2011 Regal is for Buick fans looking high and low for that perfect car. You never know when life is going to throw you a curve but the antilock braking system will always be there to help stop trouble right in its tracks. New Car Test Drive said ...We found the Regal very quiet with a very smooth ride a welcome respite on miserable commutes and a good partner for cross-country drives. It may be the quietest car in its class. Mix in a solid thud to the doors tactile clicks to the controls and a structure safe and secure and the Regal is a well-rounded package...
