The JC Wyvern was kit car built between 1983 and 1986.

The Wyvern had 1930's style being based on mechanical components from a Vauxhall Viva HC, Magnum or Firenza. The car utilised the range of engines from the 1256cc engine up to the 2279cc engine found in the Magnum. 

The chassis was constructed from 3" x 2" box section steel and was sent to the customer ready primed. The GRP work was said to be first class. 

The price for the basic kit in 1985 was £1660 and for an extra £35 you could opt for Ford Escort engine mounts which was an option from that year (Ford 1300 and 1600cc engines).

The Wyvern project was sold on in 1986 and seems to have demised at that point.
