Warren, Michigan is a town best known as the home of the Ram truck assembly plant. Yet next door is a nondescript industrial building that houses a vehicle collection like none other—and, no, it’s not full of Chryslers.

The General Motors Heritage Centre building is completely unassuming, but your perspective changes entirely when you step through its doors. This facility – it’s not open to the public, sorry – houses the history of all the GM brands from Day One.

On the floor there are at any time around 160 cars and trucks, including concepts, one-offs, and experimental vehicles. In total the collection has over 700 historically significant vehicles housed in several buildings; however, they only get shown off here.

The pieces highlighted in this floor show, bathed in the glow of neon lights, is rotated, often changing for specific events or anniversaries. For instance, front and centre right now is an assortment of significant trucks, honouring the 100th anniversary of the first production GM truck being built in August of 1917.
