Wow. They made them for a few years (probably not surprising given their McLaren-derived styling). I've got a brochure from the Australian agent, Manta Motors, which dates to the mid-70's. At that time they had 1970 VW or late Karmann Ghia suspension listed in the specs. Nett weight with a small block Chev was quoted as 1900lbs. (under 900kg!!)
