Found a steel frame laying around that someone in another shed discarded when they vacated, so turned it into a workspace for the car.

It took a couple old coversheets and a few screws plus about 40 minutes to throw together. Its got a fair amount of space under it that's good for stashing big items, stands, parts etc.

Plus I can highly recommend having a couple of robust old office chairs to roll around on while working on the car. It makes working on a lot of things very comfortable.
