W123 is the chassis designation for the midsize sedan and coupe, made from 1977 to 1985. Models included the 240D, 300D, 300TD (wagon), and the gas-powered 280SE. In my opinion, the W123 embodies the true classic era of modern Mercedes automobiles, though others may argue this purely subjective notion. The W123 gave way to the larger and more elegant W126, and then the W124. The ubiquitous 123 had a big sister, the W116, which housed the SD and SE series for roughly the same years as the 123. In a word, excellent cars, especially the diesels...but I'm a bit biased.
