just noticed on EBAY that Mills engineering are selling the rights, moulds and jigs for the MEVX5 and Surerlight range of kits which fit on MX5.
The whole package, including a finished car and a chassis, is for sale for £12k.
Seems like a bargain for a nice kit.
The superlight chassis could also be adapted to suit the MX250 kit which Chris is currently selling. This would reduce the weight of the car by 300kg as claimed by MEV.
