I know theres allot of knowledge out there and I want to tap into it. I want to purchase a Cobra in kit form or already done. I would like some opinions as to which ones are the best. I live in scottsdale and have gone to American legends and looked at super Performance mk111 and cobra 427 s/c CSX. Is the CSX worth ten thousand more for the rolling chassi? I know you have better things to chat about but I would really appreciate some help. Bob b.
