Sewell Cadillac of Dallas opened its doors in 1957 and has set the standard for luxury car dealerships ever since. Sewell has been the highest-volume dealership in the Southwest for the past 30 years. In 2014, we continued to be honored by Cadillac as the only dealership to receive the Master Dealer award for 41 consecutive years. 2014 also marked the 14th consecutive year that we earned the Cadillac Dealer of the Year award, which we have received every year since the award's inception.
