The Volvo P1800 is Volvo's most famous and popular sports car. Introduced in 1961, the "S" designation was added in 1963 (and the "P" was dropped) when production moved to Sweden. The 1800E was introduced in 1969; the "E" meant the car was now equipped with fuel injection. Later, near the end of the 1800's life, the 1800ES was introduced, a shooting brake/wagon version of the car. A '66 1800S currently holds records for high mileage; it recently hit 3,000,000 miles. This 1800S has the addition of a large canvas sunroof installed.
