Yet another Seven-esque vehicle which I knew nothing about, comes from Czech manufacturer Kaipan.  The current version is the 57 and much like a Caterham Seven, comes in varying kit configurations and uses the VW-Audi 1.8l engine as found in the Skoda Octavia (and several other cars from the VAG group).  Looking at the pictures in the photogallery, the cars look pretty good.

There was also a Kaipan 47 of which about 50 cars were produced, though it's now discontinued.
