This has to be one of the neatest web sites! A friend just shared this. This is a web site featuring the original factory brochures for nearly every American car you have ever owned. Pick the manufacturer, the year and the model. Enjoy! http://www.lov2xlr8.no/broch1.html
That's a great resource Board member @priariecanary runs a site (https://www.gransportstage1.com/) with Buick literature, ads, color charts, etc.
That's Hans' website, mentioned here onV8Buick many times before. Over the years I've sent him a lot of scans from Buick (and other US car) brochures. Click here for other car related categories on his website
Here is another amazing website with 1000's of scanned factory brochures and literature: https://xr793.com/ There is an incredible amount of information. Click through the various dropdown menus and you might be shocked at the amount of content (he says over 20,000 items). It just keeps going and going. One benefit of this website is that you can easily download & save a multiple page brochure as one easy to manage pdf file with all of the pages together. With many of the others you would have to right click and save each individual page. If you are looking for a single page and want to save it as a jpeg, then the www.lov2xlr8.no website works well.
