The (original) Daimler Limousine report from the 'Motor' magazine June 15th, 1968 is available here on this website.

This is a good place to express my gratitute to Bryan Peebles, archivist of the Vanden Plas Owners' Club. The text of this article is mainly based on the DS420 coverage in his book Vanden Plas, the Austin Years.
But I (hjt) also owe him many thanks! When I visited Bryan in 2007 he provided a wealth of copies with DS420 information from the legacy of the Vanden Plas factory for publication on this website. Credit for the items of this collection can be found on many places of this site.
