Triumph ZKC/ZKE (1970–1977)

The Triumph Stag is one of the most visually stunning British cars of the 1970s. Powered by a unique 3.0-litre V8 engine developed specifically for the car, the Stag offered genuine grand touring performance in a stylish 2+2 convertible body. The Stag was launched in 1970 and produced until 1977. The V8 engine has an undeserved poor reliability reputation — most problems stem from overheating caused by neglect rather than fundamental design flaws. A properly maintained Stag with a rebuilt cooling system and correct coolant is a reliable and enjoyable classic. Many owners fit a Rover V8 as an alternative. The distinctive T-bar roll cage and optional hardtop make the Stag one of the most elegant open-top classics of its era.
