Krakshot, after reading all the posts here I do agree that the Coaches Hurricane is the deal, but I'm saying that because I built my own Hurricane.
I researched most of the Replicas out there and most are very good, it really depends on how much work you want to do. Money wise..buy used you will save about $10,000 bucks over building yourself. ERA's are very good machines and have great resale, the Hurricane kit is the most complete Kit, very authentic and easy to build, they also will install engine mounts for whatever engine you want. These two cars were my top choices for me after all the research.
Truthfully, just buy or build the cobra you like most and you'll be happy and proud.

I'm pushing 14,000 miles on my car and it runs like a fine tuned watch.
