Since there are multiple dealerships owned by Serra Automotive Group, it is difficult to determine an overall scale of customer satisfaction. According to Better Business Bureau, the company have received an A+ rating and have only had six complaints in the past two years, all of which have been answered.
In addition to the Better Business Bureau ratings, there is information on the individual dealership Yelp pages. For the Yelp pages, the ratings range from 2 stars (Serra Toyota Scion in Farmington Hills, Michigan) to 4.5 stars (Serra Chevrolet of Farmington Hills). Therefore, the company apparently has some good dealerships to some below average dealerships.
