Despite its 17-year run and nearly a quarter million made, the Mercedes-Benz R107 continues to make double-digit gains in value year-to-year across all condition categories. These are led by the later 560 and early small- bumper 350/450 models. Low-mileage, well-sorted examples routinely approach or eclipse $40,000. Here’s a chance to get in on the hot market with an exceptionally well-maintained, relatively low-mileage SL—that has stayed in one family since new—for less than half that. It’s a pretty combination too in its triple blue with the classic bundt wheels. Find it here on Craigslist for a look-rich-cheap $18,900.
