The Wikipedia is a Wiki. This tool allows you or I or anyone knowledgeable about any given subject or topic the means to add or edit content — In this case to the world’s free encyclopedia on the web. The Wikipedia has umpteen thousands of pages currently posted on topics. Even so, If you search Wikipedia for a given item and come up empty handed then write about it and save it to the site. Who knows, other collaborators might jump in and help you to flesh it out. Kind of like leaving your initials carved into the picnic table. Here is a contribution: The Mercedes-Benz 220SE. I’m not an expert authority but I do come from a generation that remembers the era. Go ahead! Jump in!
