The Costin Amigo was a lightweight sports car built in the United Kingdom in the 1970s. It was designed by Frank Costin (of Marcos (automobile) fame) and built in Little Staughton, Bedfordshire.
Its 2-litre engine and running gear came from the Vauxhall VX 4/90, but its plywood monocoque frame and aerodynamic fibreglass body gave it a top speed of 137 mph (220 km/h), and a quoted 0-60 time of 7.2 sec.
Only eight of the cars were ever sold.
