Autodynamics was a company that made race chassis in the sixties (including a dozen mid-engine platforms for FiberFab), and then took over making the successful Deserter dunebuggy. They were also making replacement body panels for the Lotus Elan, which they bridged into a business making full Elan-inspired bodies for a shortened VW chassis, a kit which sold for $1,300 at the time.
Viv (firstname.lastname@example.org) has the 1972 one below for sale for $3,000 or best offer, writing that only about forty were ever made and that the fit and finish makes it seem more like a production vehicle than a kit car, although there are a few stress cracks that show through the recent paint job (and new windshield, gas tank, and floors). A little work is still needed, the rear brakes have to be hooked up and the wiring needs attention — don’t worry, it comes with a manual — but it seems like a good deal for someone willing to do these last little touches. The car is located in Del Rio, Texas.
