There used to be another kit car forum which had a rather legthy discussion on the 300SL. Its hard to keep track but at this time the only manufacturer of a 300SL kit is Thoroughbred Motorcars in Mt Dora Florida. Does anyone on this forum have a kit or know someone with one. I have been working on mine for several years now. Its always good to exchange ideas. You can only learn so much from the Cobra guys!
