Mills Extreme Vehicles (MEV) is a kit car design and manufacturing company based in Mansfield, UK. It was founded in 2003 by Stuart Mills. As of January, 2016 they manufacture the Exocet and the Replicar, the former an exoskeletal design, the latter a full body design inspired by the Aston Martin DBR1 of the late 1950s. Both cars use the Mazda MX5 Mk1 sports car as their foundation. They also produce an enhanced version of the Exocet, the MX150R which currently runs in a UK race series regulated by the 750 Motor Club and the MSA. Stuart Mills has designed over 20 vehicles ranging from electric commuter trikes to off-road 4x4s, some of which have been commission builds and designs for external manufacture or technological educational purposes, others have been in-house or licensed manufacture.
