Apparently the Kobra Motor Company is the outfit who acquired all of Johnex's tooling after they went under, and last I heard, was still building a car virtually identical to the Johnex.
A chassis link on their site takes you to CSC Racing, which was the same outfit who was building the chassis for Johnex. Apparently CSC has not yet modified their site to reflect the changes at Johnex, as it still indicates that the CSC chassis is being built for them.
