My copy of Build your own Spors Car on a budget showed up today. I can add it to my collection of locost books.
I have to say I find the design very appealing. It works out to be 2in wider, 4in longer, and 1in taller than a "book" locost. It has very nice lines and seems to be a very well sorted plan. There are some modified version of this plan floating around the internet that accommodate Miata rear suspension. I am leaning this way.
