Who said jeep is the only true American sports car?

That quote, "Jeep is the only true American sports car," is not definitively attributed to any single person. It's more of a commonly repeated sentiment among Jeep enthusiasts, rather than a statement made by a specific famous individual. It's a provocative claim used to highlight the off-road capability and ruggedness of Jeeps, contrasting it with the typical image of a sports car.
