I have been tracking down some of the Motion built cars of the 70s and 80s and have purchased two from Joel. They are "his and her" Motion cars used in Motion catologs and as show cars and as personel transportation. One is a 1989 Mustang GT convertiable which I think is the last car Joel Built. He did some 3rd Gen big block Camaros, a 4 door Corvette show car, some supercharged and some turbo and others. Here is a web page of the Motion Mustang GT

I may be selling this car if anyone is interested email me
Joel was building cars and also bought back some of his old cars and restored them then sold them again. I believe one collector bought 3 Motion Corvettes that Joel found and restored.
