Every gearhead has a favorite origin story, but few realize the granddaddy of them all happened on September 16, 1908, in a modest office in Flint, Michigan. That is the day William Crapo “Billy” Durant, a cigar-chomping carriage salesman turned industrial gambler, filed the paperwork to incorporate the General Motors Company. He had no idea he was about to build the house that would eventually raise the Corvette, the Camaro, and the Silverado. He just knew Buick was selling like crazy, and he wanted more.
The Buggy Salesman Who Built General Motors
Durant had not built a single engine in his life. He made his fortune selling horse-drawn carriages, of all things, before taking over the struggling Buick Motor Company in 1904 and turning it into the best-selling car brand in America within four years. Riding that momentum, Durant folded Buick into a brand-new holding company, General Motors, on this date in 1908. Within months he had swallowed up Oldsmobile, Cadillac, and Oakland, the brand that would later become Pontiac. Three years later, after a group of bankers briefly booted him from his own company, Durant roared back and co-founded Chevrolet, then used it to claw his way back into control of GM by 1916.
From One Signature to a Century of Icons
It is wild to think about now, but that single piece of 1908 paperwork is the reason gearheads argue small-block versus big-block at cruise nights today. Without Durant’s fast-and-loose empire-building, there is no Chevrolet to build the first Corvette in 1953, no Camaro to fire back at the Mustang in 1967, and no Silverado to anchor America’s truck obsession for the next century. GM’s family tree also produced the GTO, the Trans Am, the Suburban, and the Hummer, machines with wildly different missions but one shared bloodline. Just look at how deep that bloodline runs: Chevy built exactly one Camaro Z28 convertible, built as a company car for the plant’s own general manager, decades before anyone thought to build a factory Z28 ragtop for the public.

Durant’s timing was never subtle. He built GM at a full sprint, buying up brands the way collectors chase barn finds, gut instinct over spreadsheets. That approach nearly bankrupted him twice, and he eventually lost control of the company he built, dying decades later far removed from the empire bearing his fingerprints. But the outfit he assembled on a handshake and a hunch became the backbone of American performance and utility. Even now, when a Corvette Grand Sport prototype GM tried to bury can match a factory Ferrari dollar-for-dollar at Pebble Beach, you are watching the long shadow of that 1908 filing stretch all the way into a Monterey auction tent.
Why It Still Matters at the Cruise-In

None of this is ancient history to enthusiasts. Every time GM quietly discontinues a giant Silverado HD or drops a new Corvette ZR1 that breaks a quarter-mile record, it is still riding the momentum Durant generated in a Flint office more than a century ago. The Bowtie and Blue Oval crowds will keep arguing at every cookout, and somehow it all traces back to one restless carriage salesman who could not stop buying car companies. So today, whenever you happen to be reading this, raise a wrench to September 16, 1908. It is the day the GM garage opened for business, and it never really closed.
