What is a 2002 ZL1 Supercar Camaro?
A Modern Supercar With Legendary Roots
The GMMG ZL1 Supercar Camaro is a rare, high-performance fourth-generation Chevrolet Camaro that underwent extensive upgrades by GMMG, Inc., a performance tuning shop based in Marietta, Georgia. Created in 2002, this limited-edition Camaro was designed to commemorate the legendary 1969 COPO ZL1 Camaro, with just 69 cars produced—matching the original COPO ZL1 production total.
The top-tier Phase III ZL1 Supercar featured a powerful all-aluminum 427ci V8 engine and performance upgrades designed to deliver supercar-like performance. These cars also featured unique badging, striping, and specialized suspension components to enhance handling and speed. Many original owners also opted for custom paint, selecting heritage colors from 1969.
While Berger Chevrolet sold the largest quantity of ZL1 Supercars, with 28 of the 69 units, the remaining cars were sold through 12 other Chevrolet dealerships across the country. Plaques bearing the vehicle's original owner's name and selling dealership were mounted underhood, located on the driver's side strut tower.
Unlike the original 1969 ZL1 COPO Camaros, the 4th-gen ZL1 Supercars were not built directly by General Motors but were instead standard Camaros that were modified by GMMG. While unique, they are not to be considered 'COPO Camaros'.
Today, the GMMG ZL1 Supercar Camaro stands as one of the most sought-after fourth-generation modified Camaros—celebrated for its unmatched performance, high build quality, and deep-rooted connection to the Camaro legacy. Its prestige is rivaled only by Berger Chevrolet’s and GMMG’s final swan song: the legendary 2002 Berger Supercar: Dick Harrell Edition Camaro.

How many 2002 ZL1 Supercars were made by GMMG?
A total of 72 2002 ZL1 Supercar Camaros were produced by GMMG. The program began with three prototype vehicles, followed by a limited production run of 69 customer cars. This number was a deliberate homage to the original 1969 ZL1 Camaros, of which only 69 were built by Chevrolet (through a Central Office Production Order - COPO), making the modern interpretation even more collectible.
Each car was modified at GMMG’s Marietta, Georgia, facility and received extensive performance and appearance upgrades. The 69-car run was distributed through 12 Chevrolet dealerships nationwide, with Berger Chevrolet selling the most—28 units in total.

How much horsepower did the ZL1 Supercar make?
The GMMG ZL1 Supercar Camaro offered three tiers of performance. The packages were structured in distinct Phase levels, each offering escalating horsepower and performance improvements. Here’s a look at the packages and their corresponding horsepower ratings:
Phase 1: 400 Horsepower/410 lb-ft of torque
The entry-level upgrade for the ZL1 Supercar, Phase 1, started with a 427ci engine (based on the LS6 block) that produced approximately 400 horsepower. This base performance package included a modified camshaft, upgraded exhaust, and an improved intake system, making the ZL1 a noticeable step up from the stock Camaro in both sound and power.
Phase 2: 475 Horsepower/440 lb-ft of torque
Phase 2 was where the ZL1 started to show its aggressive side. With a more aggressive camshaft, optimized tuning, and enhancements to the intake and exhaust systems, Phase 2 ZL1 Supercars produced around 475 horsepower, offering a sharper throttle response and quicker acceleration. This phase was ideal for buyers looking for a stronger, more exciting driving experience without going to the extreme.
Phase 3: 600 Horsepower/575 lb-ft of torque
Phase 3 ZL1 Supercars were the ultimate expression of performance. Equipped with a C5-R–based 427ci engine, these cars delivered a massive 600 horsepower—a major leap over the previous phases. Derived from GM’s Le Mans-winning Corvette C5-R race engine, this phase was built for serious enthusiasts seeking track-ready performance, offering incredible torque and high-revving capabilities that made Phase 3 ZL1s some of the most powerful and rare 4th-gen Camaros ever built.
What does ZL1 mean?
The GMMG Camaro was named the ZL1 Supercar as a tribute to the legendary 1969 COPO Camaro ZL1. In that original model, “ZL1” referred to the RPO (Regular Production Option) code assigned to the special high-performance package processed through General Motors' Central Office Production Order (COPO) system. The term “Supercar” was commonly used at the time to describe vehicles built with exceptional speed, power, and track-ready performance in mind.
Are 2002 GMMG ZL1 Supercar Camaros collectible?
Yes, 2002 GMMG ZL1 Supercar Camaros are highly collectible. With only 72 cars produced—including 3 prototypes and 69 production units—these limited-edition Camaros represent a rare chapter in fourth-generation F-body history. Each car received hand-finished performance and styling upgrades that significantly elevated its value, and many were delivered with low mileage and carefully preserved by enthusiasts from day one.
Their exclusivity, connection to the muscle car heritage, and unique blend of modern engineering with retro flair make them especially appealing to collectors. As awareness continues to grow, so does their desirability, cementing their place as one of the ultimate collector Camaros of the modern era.
How Much Is a 2002 GMMG ZL1 Supercar Camaro Worth Today?
The 2002 GMMG ZL1 Supercar Camaro has become one of the most collectible modern muscle cars, thanks to its extreme rarity, high-performance upgrades, and direct connection to fourth-generation Camaro history. With only 72 examples produced—three prototypes followed by 69 production cars—these cars are seldom seen for sale and are highly sought after by enthusiasts and collectors alike.
At past Mecum Auctions, select examples have crossed the block, further validating the car’s collectible status. Notably, ZL1 Supercars have brought between $80,000 and $150,000, depending on the specific phase, mileage, provenance, and original documentation. Rare versions—such as Phase III cars with 427ci engines or Dick Harrell tribute builds—can command even higher prices when they appear, which is increasingly rare.
Their consistent upward trend in value and limited production numbers have secured the GMMG ZL1’s place as one of the ultimate fourth-gen Camaro collectibles—and a must-have centerpiece for any serious American muscle collection.
Is the ZL1 Supercar street legal?
Yes, the GMMG ZL1 Camaros are street legal. These modern tribute cars were built using late-4th-gen Camaro SS models and upgraded by GMMG with performance, appearance, and handling enhancements — all while maintaining street-legal status. They passed emissions testing (at the time) and retained factory VINs, titles, and registration, making them legal for everyday road use. However, some high-horsepower variants might not comply with current emissions standards in stricter states.
Is the ZL1 Supercar the Rarest Camaro?
While not the rarest, the GMMG ZL1 Supercar Camaro ranks among the most exclusive fourth-generation Camaros ever built. With limited production numbers, race-inspired engineering, and a direct lineage to the 1969 COPO ZL1, it’s revered as a modern-day legend—rivaled only by the original 1969 COPO ZL1 and the ultra-limited, even more heavily modified Dick Harrell Edition.
More Than a Camaro
The ZL1 Supercar was more than just another Camaro—it was the boldest expression of GMMG’s capabilities. It merged modern LS power with COPO-inspired exclusivity, offering customers a bespoke performance machine that felt equally at home on the track or in a private collection.
As production of the fourth-gen Camaro wound down, the ZL1 Supercar became a fitting sendoff—closing the chapter on an era of dealer-backed tuner cars and cementing GMMG’s place in performance history.
