Larry,
If you install 2 workbenches say 4 feet wide down one side or better on the wall opposite the garage doors, where will the car go? My dad built the same size garage 35 years ago....I learned from him. It looks like a nice finished garage. Add lots of LED 4' overhead lights. I put in 2 400watt metal-halide high bays, but recently converted them to 100w LEDs. All my other lights are 8x 4 lamp T8s which are now all LEDs. No more ballast replacements and cold weather doesn't affect them. Don't forget room for air compressor and lines. If you drop your power cord for lifts (240V) from the ceiling they will not be on the floor as a trip item. Ceiling fan? Oh yes...nice finished walls for art work.
A friend of mine is finishing his 3rd garage building at 30x60 feet. He still doesn't have enough room to do the level of car care he does. I suggested he not buy anymore cars. Enjoy your new space.
