Esargi was a small British kit car company established in 2008 and based in Gaerwen on the Isle of Anglesey, Wales. Esargi promoted itself as a manufacturer of modern-styled sports cars and eco-vehicles offered in component kit form for self-assembly. Its marketing emphasized lightweight construction, affordability, and the thrill of building a road-legal sports car at home. Esargi announced at least one roadster-style model concept, which was intended to combine sleek contemporary styling with accessible engineering. Promotional text described it as both a sports car and a practical eco-vehicle option.
