Andrew, This is the second Cbbra replica I've built. And I don't remember how many old Fords' I've fixed or rebuilt. My last Cobra was from a company called Classic Roadsters, out of Fargo, ND. A very high quality kit, very simple, and resonably priced. When I started my research for the first kit, I looked closely at FFR. I quickly discounted them because there were some design flaws (in my opinion) for what I was looking for.
This time around - 4 years later- I again looked at every manufacturer in my price range. I chose FFR for a number of reason. All the design flaws had been fixed with the new chassis. And I really like the company and their personnel.
The single donor priciple is the biggest selling point. With the kit ($12000) and a 86-93 Mustang (about $2500), you have everything except gas, oil, and paint. No chasing parts, no digging through boneyards, no sending Summit Racing huge checks. Such a deal. Easy to build for well under $20,000.
Unfortunatly, most of us here tend to over think, overdesign, and overbuild our cars. It's the old "While I'm at it" syndrome. And I'm no exception
Take a look at all the companies/kits out there. Make a special effort to visit the companies and meet the people, and put your hands on the product. Thats how you'll find the right one for you.
