The Rare Rides series has covered every generation of Aston Martin’s Lagonda four-door except one. In the Sixties, the Lagonda Rapide helped to define the super sedan class: A grand tourer that could sweep four passengers and their luggage across Continental Europe with ease.

Then there was the late Seventies Lagonda, which had a long production run through 1990. Advanced electronically, that Lagonda was too ambitious and generally earned its reputation as a good-looking, expensive disaster. Finally, there was the Lagonda Taraf, a large sedan designed specifically and cynically for the UAE market. It was built to extract maximum dollars from oil barons and the like. Great success!

But between Lagonda Rapide and Lagonda was a missing link. It was called the Lagonda Series I and is the rarest Aston Martin Lagonda ever made. And one is for sale.
