The Transporter has been a mainstay of the LCV range since 1950 and sells in both kombi and van forms. Production is still around the 175,000 point. It has been in it's 6th generation since 2014.
The Caddy closely follows it in production volume with the same two classifications and 150,000 were made in 2015. This - the third generation - has been around since 2004. The Caddy started life in 1980.
The Amarok pick-up is a solid selling part of the LCV range. It is a recent addition, coming in at 2010 and has established a moderate - but not spectacular - following.
Finally the Saveiro pick-up made for Latin America, which is based on the Gol and made in Brazil. Recently it was changed in classification from a light commercial to a car by VW, but for now I have kept it as a LCV.
