1999 Vector SRV8
This is the 1998 Vector SRV8, the lone functional prototype and the final machine to wear the Vector badge. Though spotted occasionally in the wild, its true whereabouts remained a mystery until 2025. In 2021, we contacted the car’s owner—Jake Welty, son of Vector’s final proprietor, Randy Welty—in hopes of learning more and potentially acquiring it for one of our clients. Jake still possessed the SRV8, gifted to him on his 16th birthday, and initially had no desire to let it go. After four years of conversations between Rare Cars Only and Jake, a landmark deal was finally struck: the SRV8, three long-lost Vector M12s, and the one-off M12 ASR GT2 race car were sold to our friend Matt Katz (@caretakerscollection), marking what may be the largest single Vector transaction in history and an extraordinary moment for everyone involved. The 1999 Vector SRV8 (Chassis 001) shown here effectively represents the grand finale of the Vector story. Designed as a significantly re-engineered successor to the M12, the SRV8 featured all-new aerodynamics, a revised suspension, and a modified 5.7L GM LT1 Corvette V8 producing roughly 350 hp in a lightweight 2,750 lb package. The car was largely hand-built, with a bespoke rear wing, air scoop, side ducts, front splitter, and a design philosophy the company termed “Street Race Legal,” giving meaning to the SRV designation. Beneath its vivid yellow, sharply tapered bodywork lies the only American-built Chevrolet V8 ever installed in a Vector, embodying a final engineering pivot meant to revive the brand in its closing years. As the last road-registered Vector and the final Vector ever constructed, it stands as the definitive bookend to a marque driven by ambition, ingenuity, and the relentless belief that America could build a world-class supercar. Once a unicorn known only through scattered photos online, it now returns to the world ready to be preserved, driven, and appreciated once again!
1998 Vector M12 ASR GT2 Race Car
This is the Falconer V12–powered 1998 Vector M12 ASR GT2 Race Car, a frantic, one-off effort engineered from a pre-production M12 shell in a last attempt to keep Vector relevant in IMSA competition. After more than twenty-five years hidden away, Rare Cars Only uncovered the car under the stewardship of Jake Welty, son of Vector’s final owner, Randy Welty. Long thought lost, negotiations to bring the car into the public eye began in 2021, and by 2025 it finally became available for purchase. It was then sold to our friend Matt Katz (@caretakerscollection), who intends to restore the machine to its former presence as a symbol of American entrepreneurship and racing ambition. The car is powered by a Falconer V12 engine, adapted for GT2 regulations. The rough welds, and uneven hand-cut paneling now serve as physical evidence of a company fighting extinction while still daring to compete. The ASR’s short but intense 1998 season tells the story of a team improvising at every turn. Debuting in white at Sebring with a body resembling a road-going M12, it was entered by Jon Lewis and finished 44th with Bill Eagle behind the wheel. After that, the bodywork was heavily revised, gaining a more extreme aerodynamic profile for its Las Vegas outing, entered by American Spirit Racing and driven again by Eagle to a 21st-place result. Although slotted to appear at the 2 Hours and 15 Minutes of Homestead, the car failed to attend, re-emerging instead in black for the 3 Hours and 45 Minutes at Road Atlanta. Entered once more by Lewis and co-driven by Eagle and Randy Pobst, it finished 19th—its final competitive result. A last planned entry, the 1 Hour 45 Minutes Minneapolis round, saw the car repainted white into the livery it still wears today, but it never made the grid. Over time, fragments of its early bodywork surfaced at auction in 2020, though the car itself remained missing until our rediscovery in 2025. Now, after decades of silence, this unicorn is finally poised for resurrection.
1999 Vector M12-014
This is the 1999 Vector M12 chassis 014, perhaps the most battle-scarred but historically revealing of the five Vectors recently re-discovered by @rarecarsonly within the hidden Vector collection. Chassis 014 is infamous for the final-day employee joyride that unfolded in 1999, just hours after Vector ceased operations; an employee took the barely driven car—showing only around 800 miles—and managed to launch it into a ditch, forever preserving its wavy fiberglass, missing headlights, and battered nose as physical evidence of the company’s chaotic last moments. Yet beneath the damage lies a remarkably original, sub-1,000-mile M12 that, with careful preservation, stands as a 25-year-dormant barn find unlike anything else in American supercar history. This M12 is one of three examples Rare Cars Only sourced from Jake Welty, son of Vector’s final owner, Randy Welty, who unknowingly became the steward of some of the last surviving pieces of Vector’s story. From 2021 through 2025, negotiations unfolded until our friend Matt Katz (@caretakerscollection) acquired all five cars—the SRV8 prototype, the one-off ASR GT2 race car, and three M12s—marking a landmark moment for Vector preservation. As with chassis 009, the story of 014 cannot be separated from Vector’s turbulent corporate history: originally founded by Gerald Wiegert in 1971 as Vehicle Design Force before evolving into Vector Aeromotive, the company produced a series of American wedge supercars—the W2, W8, WX-3, and eventually the M12, which emerged during the controversial Megatech era. In 1994–1995, however, Randy Welty purchased the company back from Megatech, becoming Vector’s sole owner and attempting to revive the marque through new models, racing plans, and structural reorganization while still relying on Lamborghini engines during a time when Megatech briefly owned both companies. Welty’s efforts prolonged Vector’s life by several years, but when Lamborghini’s supply ceased and funding dried up, production ended in 1999. Chassis 014, frozen in time with its dents, cracks, and abandoned potential, tells the story of those final days more vividly than any pristine example could. Now, for the first time in decades, it is ready to be restored, preserved, and returned to the world as one of the most compelling survivors of America’s most ambitious supercar dream!
1997 Vector M12-009
This incredible car is a 1997 Vector M12, chassis 009—number nine of just seventeen total M12s ever built, including fourteen production cars and three prototypes. It is one of three lost M12s recently re-discovered by @rarecarsonly within a hidden five-car Vector collection belonging to Jake Welty, son of Vector’s final owner, Randy Welty. From 2021 through 2025, careful negotiations unfolded until our friend Matt Katz (@caretakerscollection) secured all five cars—the SRV8 prototype, the one-off ASR GT2 race car, and three M12s—marking one of the most significant Vector acquisitions ever made. Chassis 009, finished in its original teal over matching teal leather, stands today as one of the cleanest and most complete surviving M12s. It remains the only M12 in the world finished in this color and has not been seen publicly since its appearance at the 1997–1998 Mexico Auto Show. Its Lamborghini-sourced 5.7L V12 and Peter Stevens–penned bodywork finally receive the preservation they deserve. Vector’s story began in 1971 when engineer Gerald Wiegert founded Vehicle Design Force, later renamed Vector Aeromotive. Over the next two decades, he introduced a lineage of angular, aerospace-inspired American supercars: the Vector, W2, W8, Avtech WX-3 and WX-3R, and several experimental prototypes. But by the mid-1990s, Vector’s future became entangled in corporate turbulence. Indonesian-backed Megatech gained control in 1993, moved operations to Green Cove Springs, Florida, and launched the M12 project using a Lamborghini chassis and V12—made possible because Megatech owned both companies at the time. Peter Stevens, famed designer of the McLaren F1 and JaguarSport XJR-15, was brought in to reinterpret the WX-3 into a production-ready machine, resulting in the M12’s distinctive look. What is often forgotten, however, is the pivotal role of Randy Welty. In 1994–1995, Welty purchased Vector back from Megatech, gaining full ownership and attempting to salvage the brand’s identity. He pushed for new models, racing programs, and long-term development, determined to keep Vector alive after years of instability. His efforts extended the company’s lifespan by several years, but despite his best attempts, the loss of Lamborghini engine supply ultimately forced production to end in 1999. Chassis 009 stands today not only as a rare surviving supercar, but as a testament to the final years of an American dream that refused to quit.
1997 Vector M12-003
This is the 1996 Vector M12 chassis 003, the gloss-black company car personally driven by Vector’s final owner, Randy Welty, and the only M12 that was regularly exercised in public during the brand’s turbulent final years. Lightly chipped from promotional miles, chassis 003 is one of the rarest time capsules of Vector’s last chapter—a car scarcely photographed and seen publicly only twice in period, first at the 1996 Mexico City Auto Show and later at a minor league baseball game outside Jacksonville, where Welty famously drove it onto the warning track during the seventh-inning stretch and launched t-shirts into the stands. Chassis 003 was one of three M12s re-discovered by @rarecarsonly in 2021 inside the hidden Welty family collection, preserved by Jake Welty for decades until a landmark 2025 deal in which our friend Matt Katz (@caretakerscollection) purchased all five surviving Vectors: the SRV8 prototype, the ASR GT2 race car, and three M12s. Its story mirrors the chaotic corporate reality Vector faced in the mid-1990s, when Gerald Wiegert was ousted and Megatech—via its holding company V’Power—moved operations to Florida and pushed the M12 into rushed production using Lamborghini engines. By late 1996, only five updated M12s had been completed before finances collapsed. In 1997, Tradelink International secured an option to take control, enabling ten additional M12s to be finished before the supply of Lamborghini V12s evaporated. Complicating matters further, Lamborghini itself was sold to Audi in 1998, severing the Megatech era entirely and leaving Vector stranded between V’Power, Tradelink, and an engine supplier now controlled by a German giant with no incentive to support Vector’s survival. By 1999, the remaining employees, the unfinished SRV8, and the stalled production line sat in limbo, marking the quiet end of America’s most ambitious supercar experiment. Rediscovering chassis 003—alongside its four siblings—wasn’t merely a transaction for us at Rare Cars Only but a responsibility to ensure Vector’s fractured history didn’t fade into obscurity. We are honored to have played a role in securing their future, and we encourage everyone to follow Matt Katz and the Caretakers Collection as restoration, preservation, and exhibition of these five extraordinary machines now take shape.
