Lagonda 4 litre Rapide
 

There was then no Lagonda made for nearly four years until the Motor Show of 1961 when the 4 litre Rapide was introduced (96 x 92mm, 3995cc). This was virtually a four door DB4 Aston Martin and had nothing in common with earlier models. The only major difference from the DB4 apart from the styling lay in the De Don rear suspension, different carburation and the availability of automatic transmission. 55 were made in 1962-1964.
