In 1989, Wiegert's company, now known as the Vector Aeromotive Corporation, began production of the W8, an evolution of the W2. Financial backing came from public stock offerings and various lawsuits including suits against the Goodyear Tire Company (trademark infringement with the Vector brand of tires) and Vantage cigarettes.[3] Two W8 prototypes were made, of which only one ran.

One black W8 was sold to famous tennis player Andre Agassi. Since Vectors were hand built, each took some time to finish, but Agassi demanded that the company deliver his W8 as soon as possible.[5][4]

Vector delivered the car as promised. Company representatives told him that he could display it, but warned him not to drive it until the final work was completed. He ignored the warning, though, and drove it hard around his yard. As a result, the car's 600+ hp engine backfired, causing the destruction of the exhaust system and the rear interior.[5]
