I just found this You tube vid, Its a pretty good description of the car.
I know and understand what you mean by the expense of this. I can't pull out 30K either. My hope is that this type of design will catch on. I had thought of this myself. Only I was thinking of using my beemer engine and rear wheel. R65.
The teardrop shape looks good also. I'm not sure they could patent "shape"
anyway here it is,
