With most automakers, a claim that one of their cars was able to drive 31,000 miles in eight days with no breakdowns, at an average speed of 154 miles per hour... well, you'd probably call bullshit. But when Mercedes-Benz makes a claim like that, folks tend to believe it (especially back in the 80s, when this ad was made). No wonder a 190 of this era finished in the Top 10 at the last Altamont 24 Hours of LeMons! Hey, is that soundtrack from Dark Side Of The Moon?
