As said before me, the badging isn't what's important here. And since none of these replicas have a Porsche vehicle identification number and it's not like you'll be welcomed into the fold (or with some even respected for building/owning a car that's a lot of fun), why worry about it? The beauty here is you get to build it how you want, in the style you want, and drive around in a car that's affordable and you don't have to worry about your investment that's worth as much or more than a house in your neighborhood. You wrote, "ALSO I KNOW MY SUBJECT WILL BE SCORNED UPON BY PURISTS"; those are good words to know going into this. Remember those words as you are driving around all over the place, while most metal Speedster owners are afraid of taking them out into traffic for fear of damaging their investments.
Oh, yeah; and Welcome to the madness. Al
