Three years plus on from my initial post, one add on I would say is that Henry has had his fabulous Coupe up for sale for at least a couple of years that I can recall now.
Now Scifab has ceased to exist I believe they (Aero's) will become increasingly more difficult to move on unless someone else starts remanufacturing parts for the Aero chassis, as the factory support seems a little lacking from what I can gather from owners.
