Ecosse Car Company was a British automotive manufacturer based in Knebworth, Hertfordshire, that operated from 1988 to 1990. The company emerged following Ford's acquisition of A.C. Cars, which necessitated a rebranding of the separate entity that held the rights to produce the ME3000 sports car.

Under the leadership of John Parsons and former B.R.M. technical director Aubrey Woods, Ecosse developed a significantly revised version of the ME3000 known as the Signature. This model featured a more rounded fiberglass body that incorporated carbon fiber for added strength. The vehicle was built on a monocoque chassis and utilized a double wishbone suspension system at both the front and rear.

In a notable shift from its predecessor, the Signature replaced the original Ford engine with a 165 bhp Fiat Croma Turbo engine, marking a new direction for the brand. Despite its innovative designs and engineering, Ecosse Car Company ceased operations shortly after its inception, leaving a brief but distinct mark in the automotive landscape of the late 1980s.
