Well I was hooked on cars at an early age having started racing 1/4 midgets in northern California at the age of 4 (same year I started kindergarten ~'56.) My Dad was always turning wrenches for some stock car or another and we went to the stock car races nearly every Saturday night and raced 1/4 midgets on Sunday afternoons.
I got hooked into the Daytona 24 hours just a bit after you Mike: I went to high school in central Florida and started going to the 24 Hours when I got my drivers license around '67. There were still a few Ford GTs running then, but the big rivalry was between the Porsche 917s and the Ferrari 512s. I have wanted to build a mid engine car ever since then having sent off for my 1st info packet for the Amante GT in '69 (found most of the material just before I bought the Sabre.) When I reached the point that it became feasible, I considered others, but the GT40 seemed to most well thought out, reasonably engineered and doable. Like others have mentioned, Cobras seemed to be too common and I wanted something that would allow me to not to meet myself going down the road (and it isn't mid engined.) The Fiero based cars were just too kludgy or were all show and no go.
Truth be known, if I hadn't lost me medical, I would have probably built an airplane, but since I couldn't legally be pilot in command, I went back to the original idea of the mid engine sports car. The rest, as they say, is history. Even with all the hassles, blood, sweat and tears that have gone into getting this car to the point it is, setting in the garage as I type, I am glad I did it and I find it quite satisfying to have accomplished it.
