I was reading and old copy of COBRAS (spring 1993Vol 1 #1) and said that the rarest Cobra was the FIA 289 as there were only five built for the 1964 season.OK so I get the six Daytona coupe's but what about the "one of" Flip Top Cobra with the aluminum 390 FE and the Super Coupe or even maybe the AC coupe(which I think has better lines than the Daytona). This is not about price just what is the rarest Cobra??
