The Vector M12 is a sports car manufactured by Vector Aeromotive under parent company Megatech, and was the first car produced after the hostile takeover of the company from Jerry Wiegert by the Indonesian company Megatech. The model was produced from 1995 to 1999, when production was halted due to slow sales of the car. The production totaled 17 units including the prototypes.

Vector Motors Corporation was an American automobile manufacturer originally based in Wilmington, California. Its history can be traced to Vehicle Design Force, which was founded in 1978 by Gerald Wiegert. Vehicle production by Vector Aeromotive began in 1989 and ceased in 1993. The company was later revived as Vector Motors Corporation, and has continued to develop sports cars. When founded, Vector represented America's first attempt to compete with European performance car manufacturers such as Ferrari and Lamborghini. Altogether around 50 Vector sports car models were developed and produced during the 1980s and 1990s including some racing versions mostly built using American made components.
