When I do research for articles, AutoHunter Spotlights, and Pick of the Day pieces for this website, I typically consult the particular vehicle’s window sticker, brochures, and press kits for specifications and information. Another resource full of helpful facts—about General Motors vehicles—is the GM Heritage site.
GM Heritage tells you the story of company founder William Durant and how he built the American automotive giant. Various short summaries highlight key moments in GM’s first 100 years, such as when Durant regained control after a six-year absence, the founding of the Milford Proving Ground in 1924, and the debut of the Buick Y-Job, “the first step in the evolution and popularization of concept cars within the automotive industry.”
There’s also a section devoted to some of the notable Chevrolet cars and trucks, Oldsmobile, Buick, Cadillac, GMC, Pontiac, and concept vehicles in the GM Heritage Collection. Those include a ’31 Cadillac V-16, ’63 Corvette Stingray, and ’70 Buick GSX. Each one has its own short write-up and small gallery of pictures.
What I’ve found the most useful on a few occasions is the GM Heritage Archive, which holds “more than 250,000 unique historical documents consisting primarily of product catalogs, sales brochures, press materials, promotional records, engineering information and service information.” Although its 900-plus Vehicle Information Kits don’t cover Pontiac, Buick, and GMC, they contain detailed technical and marketing information for many Chevrolet, Cadillac, Oldsmobile, and even Geo vehicles (how that brand made the cut and Pontiac didn’t, who knows?).
Want to know the valve timing of the 1955 Chevy Second Series trucks’ 235.5ci I6 engine? The info kit has a diagram of it. If you want to read the press release about the ’57 Cadillac Eldorado Brougham, you can. Need to brush up on your 1970 Oldsmobile option codes? Click here!
Those are just tiny bits of the information you can find on the GM Heritage site, which you could spend days exploring, stuffing your brain with useful facts and figures from General Motors’ long history. I know I’ve learned a lot from it. I look forward to learning even more and sharing some of that knowledge with you.
