This reminds me of when I had a Dodge van setup with computer and Gerber plotter. I had computer loaded with Aurora Graphics vehicle graphics designs and a vehicle outline program. I pulled into car sales places and salesmen could preview on the monitor an exact vehicle, in color, from their stock with graphics I suggested. They'd usually line me up half a dozen vehicles for graphics. This business works well in a large metro area with lots of dealerships and smaller lots. In six months I had built up a somewhat steady route of half a dozen dealers before I moved onto something else. I've often wondered what it would have been like if I had stayed with it.
