QOTD? Does Anyone Remember A Ford Granada vs. Mercedes Comparison Test By Airplane Pilots?

Ford relentlessly compared its Granada to Mercedes, such as this utterly silly test to prove that it rode as quietly as a Mercedes 450 SE. How about performance, handling, braking, etc.? Never mind…. Anyway, I’ve been contacted by a writer  doing research for an upcoming article of a related (current) matter. She heard about a comparison test that Ford set up for airplane pilots to drive both the Granada and a Mercedes at a racetrack in the Denver area, but one of the pilots lost control of the Mercedes.  The ad did run (without the crash, presumably), but the writer can’t find it anywhere. Does anyone remember it?
