What is a GMMG Camaro?

A GMMG Camaro is a fourth-generation Camaro modified by the performance shop, GMMG, Inc. Their facility was located in Marietta, Georgia with the company being formed in 1998 by enthusiast Matt Murphy. It closed in 2011. 

Their efforts were launched through a partnership with the Berger Chevrolet in Grand Rapids, Michigan. GMMG was tasked with creating a limited edition run of 2000 model-year Camaros to celebrate the historic dealership's 75th anniversary.


From there, GMMG would create several other small batches of special Camaros for Berger along with other Chevrolet dealerships including Tom Henry Chevrolet and Earnhardt Chevrolet.


The GMMG shop also created several performance-oriented limited editions of Pontiac Firebird Trans Ams for Carl Black Pontiac, located in Kennesaw, Georgia. They also created a run of bright orange Chevrolet Silverado pick-up trucks in conjunction with major home improvement retailer Home Depot.  

GMMG Camaros are highly sought after by collectors and enthusiasts due to their rarity and high performance. Only a limited number of GMMG Camaros were produced, and each car was custom built to the buyer's specifications.

Identifying a GMMG Camaro

There are several ways of identifying a fourth-generation Camaro modified by GMMG. One way is inspecting the driver's door jam for a numbered brass tag. These were installed by GMMG technicians and recorded in an official registry. 

Another indicator is exterior badging. Many times GMMG installed a red, white, and blue Yenko-inspired crest badge on the rear taillight panel, on the driver's side. The cars also received numeral graphics on the rearview mirror and on the base of the windshield.

A third way is through original documentation which could include GMMG's second and third selling stickers. The second selling sticker will detail the package contents with the third selling sticker detailing above and beyond options installed. Both will contain data that correlates to the individual vehicle.

Inside the driver's door jam, GMMG technicians riveted numbered door tags to indicate vehicles modified through their shop.
