Paul Bass ran a 1958 Edsel convertible #45 in the 1959 Dayton 500.
Bill Stroppe/Ray Swift ran a 1958 Edsel in Baja, I believe it was mounted on a ford truck frame.
There is a 1958 and a 1959 Edsel that claim to be the world's fastest Edsel, I think I saw them on YouTube
My grandfather owned 6 of them in his lifetime, some would be worth big bucks today, including a really sweet 1958 black convertible with red interior that my uncle drove throughout High School, until he opted up to a 1962 Chevy Impala SS 409
