DewayneP, has given good advice. A few additional pieces of equipment are a brake lathe, alignment machine, roll around torch, maybe a mig welder, battery/charging system tester, used oil tank, some shelving but not too much, bench grinder, ac machine, coolant flushing machine, transmission flushing machine, brake rotor and drum micrometers, good floor jack, jack stands, engine stand, engine hoist, and battery charger. When we opened we bought a used forklift which we used for 9 years until it laid down on us. It was very useful but not a necessity so I did not replace it.
