About the Triumph 1800 Roadster
The Triumph 1800 Roadster was the first post-war model from the Standard Motor Company under the Triumph name, designed to compete with Jaguar. Its most distinctive feature is the 'dickey seat' in the rear, which includes its own folding windscreen to protect passengers sitting outside the main cabin. The car features an aluminum body built using techniques from wartime aircraft production due to steel shortages. It offers a relaxed, period-correct driving experience characterized by its column-shift gearbox and soft suspension.
