You want safety?? Buy a Volvo!!!. There is no such thing as a "safe" Cobra. The body offers no protection other than from the elements(and then not from all of them!) Get a copy of "The Complete Guide to Cobra Replicas" (
www.cobracountry.com)
Most mfr's show a picture of their chassis in this book. The best one as far as "safety" goes appears to me to be RU Car Crafters Inc. Their "outriggers" (where YOU sit) appears to have more and bigger structural members, and there is an impressive metal structure in the doors, a feature I don't see in any of the others.
Like Doug 1 said, "Drive it like a motorcycle"!!
Thats what they are, 4 wheeled motorcycles, the difference being they don't tend to fall over when stopped!!!
