I'm currently in the market for my first Cobra. I've already found some real nice pre-owned Superformance but have written them off because they were titled as 2001. From what I understand, I will have the best luck if I can find one titled as a 65-67. Some guys are telling me it doesn't matter what year the chassis is, as long as the engine block is dated pre-1980? I'm not real comfortable that a DMV teller is going to waive my emission requirements because of the engine age???
