Not part of the RROC meet, but only a 2 ½ hour scenic country drive from Detroit is The Gilmore Car Museum, located in the rural hamlet of Hickory Corners, Michigan. The museum houses one of North America's largest collections of classic and vintage automobiles. Over 300 vintage and collector vehicles and motorcycles from all eras are on display in over a dozen vintage buildings located on 90 acres (36 ha).

Exhibits range from the early cars of the 1890s, to the Duesenbergs, Hudsons, and classics of the 1940s, 1950s, and 1960s, as well as automobiles built in the "Other Motor City - Kalamazoo." Also on display is a vintage Franklin dealership and the largest gallery ever dedicated to the Model A Ford. Featured are the Dust Bowl and Great Migration vehicles of the 1920s and 1930s, a 1948 Tucker, vintage pedal cars, and the Eldon and Esta Hostetler Hudson Motor Car Collection. There is also an expansive collection of hood ornaments that is likely the best on earth. Vintage motorcycles are also featured in their own building. There is truly something for everyone.

On site is a 1941 Blue Moon Diner and a re-creation of a 1930s Shell Gas Station, where gas is always 18 cents a gallon.

Admission to the Gilmore Car Museum is a few dollars and gives the visitor access to seven independent auto museums located on its 90-acre historic campus. They are the Gilmore Car Museum, Classic Car Club of America Museum, the Pierce-Arrow Museum, The H. H. Franklin Collection, the Model A Ford Museum, Lincoln Motor Car Museum and the Cadillac LaSalle Club Museum.

These Museums are spectacular in every way and must are a must-see for all visitors to the region.
