Back in the 1990s, the competition against the Buick Grand Nationals (and other Turbo Regals) was fierce.
There were some “Team Mustang vs Team Grand National” racing events put on.
Always a fun time, sometimes the Buicks won, other times the Mustangs won.
Souvenir commemorative tee shirts were a popular product at these events, available in assorted colors and designs. Some shown below.
Other various vintage Buick themed t-shirts were created over the years since then (although not near as many as are being made nowadays).
A few different examples are represented below.
