About the 1970 Triumph Stag

The Stag remains one of Triumph's most ambitious and controversial projects, a luxury grand tourer designed to compete with Mercedes SL-class cars. Giovanni Michelotti's stunning design featured a distinctive T-bar roof and flowing lines that still turn heads today. The 3.0-liter V8 produced 145 hp, but the engine's reliability issues became legendary, often overshadowing the car's considerable charm. Only 25,939 examples were built between 1970-1977, making the Stag relatively rare today. However, modern knowledge and aftermarket support have largely solved the original cooling and head gasket problems, transforming the Stag's reputation. Well-sorted examples now command strong prices as collectors appreciate the unique combination of Italian styling, British character, and V8 soundtrack. The Stag's rarity, distinctive appearance, and improved reliability make it an increasingly attractive classic for those seeking something different from the usual British sports car formula.
