The museum is definitely a destination where you can spend a whole day going through all the different buildings. The variety of things you can see is simply amazing. You can see the engine GM put into a WW II tank. You can see an airplane powered by a Ford Model A engine, the Pietenpol. You could make it from a kit.
Need a compressor for the shop, or for sandblasting a car frame? See the kit you could buy to make one from a Model A engine. Two cylinders work as normal, gasoline-powered, while two cylinders are the compression system to turn-out prodigious CFM. And since you use roughly the front-half of a Model A, it already is made with two wheels for mobility. Actually, it isn't the steering front axle which is used.

There are entire buildings devoted to various manufacturers. See the Lincoln V-12. Like something in the GM area? An Eldorado with a 500 cu. in engine, 1970 (I had one, I sold it to a friend who worked at the GM Design and Tech Center. He flew to Ft. Lauderdale and drove it back to MI. One of his co-workers, went rummaging around in his desk, and pulled-out an emblem he had designed for it, and he had kept it in his desk, for decades.
Be sure to see the Franklin collection, air-cooled, powerful engines for the time, and one creative British fellow built an entire Franklin car using blueprints from the factory. He wanted a specific body style for a Franklin powerplant, so he built one.
There is a Pierce motorcycle, built before WW I, using the frame for storage of fluids. It began as an offshoot of Pierce-Arrow automobiles, and then separated completely. They have two of the four-cylinder models, America's
first four-cylinder motorcycles.
Lots more to see in all the buildings. And outside, they have a free parking/admission weekly car meet.
