I would add Unique to your list also. They have been around a long time and build a quality car with IRS. Exterior is near perfect IMO. Interior is good but not as original as ERA and probably the Hurricane also. But, as good or better than FFR depending on how original the FFR builder was seeking.

FEs are kind of having a come back it seems - I guess due to the interest in Cobra replicas and restoring old Ford musclecars and pony cars. They have a few odd ball and quirky details and are best left to someone with real engine building skills or a FE specialist. But there isn't anything that looks better in a Cobra especially if you are seeking a high degree of faithfulness to original details and appearance. Some will even argue they sound different and maybe they do due to their firing order and other things.

Good luck.
