Frazier vs Ali
Yankees - Red Sox
Cardinals - Cubs
Bears - Packers
Ford - Chevy - Chrysler
You name the rivalry........... It's part of the Human Competitive Spirit..... quite frankly, I am surprised much of the recent revelations took so long to become public in today's age of technology. Hell, we (Car Folks) knew these rivalries have been going on for many decades.
That's why we have the Camaro, Mustang, and Challenger as our competitive focus..... Pick a model, each brand is in their at some level.
