Triumph Stag
The Stag was new for 1970 and in production until 1978. The market was pretty impressed by the new model, which featured cool styling and open-top driving but still enough room for four adults and their luggage. The Stag had a 3.0-liter V8 engine with 145 hp barely enough. With its muscular appearance and V8 rumble, the Stag looked like a luxury muscle car and attracted some buyers (via SOC).
Unfortunately, pretty soon, owners experienced the Stag’s notorious unreliability, which, along with its higher price, sealed its chances on the American and global market. When production ended in 1978, only 25,000 cars left the factory.
