What the Mark of Excellence Award Means to You

A Third-Party Stamp of Approval — Not Just Our Own Claim

The Mark of Excellence isn't something dealerships can just claim about themselves—it's awarded by General Motors based on real performance and real customer feedback. Only a select group of top dealerships nationwide earns it each year.

Proven, Not Promised

GM only gives this award to dealerships that achieve strong sales performance and high customer satisfaction scores. In other words, real customers had great experiences here, and GM verified it.

It's Not Just About Sales

The award also factors in how customers rate their service department visits, so you can trust the great experience continues long after you drive off the lot.

Independent Validation You Can Trust

Anyone can say "we're the best dealership around." This is different—it's General Motors itself recognizing Group 1 Buick GMC South out of dealerships across the entire country.

Peace of Mind for a Big Decision

Buying a vehicle is a major investment. Knowing a dealership has been independently recognized for customer satisfaction takes some of the guesswork out of where to shop.
