Triumph Spitfire 1500 roadsters from the model's debut year in 1967 sell between $6,400 and $6,900 as of September 2015. Newer Spitfires tend to sell for a few hundred dollars more than older examples, however. A 1979 Spitfire sells for an average of approximately $7,750.
The Triumph Spitfire 1500 was produced from 1967 to 1980 and was powered by a four-cylinder engine producing between 50 and 70 horsepower. The Spitfire 1500 was produced in relatively high numbers as compared to many classic automobiles, so prices for this car have not appreciated as drastically as that for other models from its era.
