Kit Car magazine went under, well their publisher decided to no longer produce it. Now there is Kit Car Builder which covers a wide variety of kit cars. They can be found online at
http://www.kitcarbuilder.blogspot.com/, I subscribe to the print version and really like it especially for the reference material available. I believe the photog of Kit Car Magazine and a local photographer are creating an online magazine that will be out soon, can't remember the name of it though.
