I remember the Sherwood Ford jingle as, "He gives a better, better deal on a better, better car, and he sells at a better, better price price. He gives a greater, greater deal on a greater, greater car--so good, good, you got to say it twice twice." Naturally, a "Sherwood Sherwood Ford Ford" tag followed that jingle in the radio commercials.
I can't say that's one of my favorite commercial jingles. Decades later, however, I still remember it, so that's effective advertising...
...Or maybe not, as I drive a Toyota.
