Hey David, I did just what you're doing & made research for my new GT 40 a top project. I live in the US & looked @ a lot of GT's & talked with the owners. In the end I chose the new Backdraft CAV. CAV is run by Auto Futura & built in South Africa.Backdraft which builds Cobra's is the U.S.
has joined in a deal with CAV to produce the BDR GT.In the US this car come as a complete roller which is what I was looking for. I know that in your country you can purchase the car in kit form or different levels of completion. The fit & finish on the CAV is a 10 all around. Also they have the most interior room with standard leather,padded dash & A/C . The BDR comes complete with the wide hip option, 17" wheels ,paint & stripes plus all the new CAV standard features that began in the # 100 series cars. Anyway there are lots of great GT 40 builders so do your homework & have fun with your build. here is the CAV web link
