Production figures in 1976 and 1977 dropped steeply compared to the figures in the earlier years. The major reason was the shortage of bodies delivered to VandenPlas. Several articles in the Carriagecraft magazine comment on this. Delivery waiting time was up to 9 month!

1977 was the year of The Queen's Silver Jubilee. Demand for the limousine was great, especially from the hire trade in London that had to cater for the many official events in relation to the jubilee.

First the February 1977 price list, publ. No. 3190/D. Its format is similar to the 1976 price lists.

This price list from May 2nd, 1977, has publication number 3190/E.

The list of limousine options has grown, and now the DS420 limousine has one and a half page in this price list. We show these above each other. The other pages can be enlarged by clicking on them.

This price list has three pages on each side, and is folded twice. On one side is, from left to right, the Limousine page, the Supercover page and the front page. The other side has three pages for the Saloon and Coupé models, of which the rightmost one is shared with the Limousine.

The basic price for the limousine has not changed, but all optional extras got a 5% price increase.

The last price list is from December 19th, 1977. It has publication number 3190/G. The format has shrunk to four pages instead of six. The limousine options did not change, but are printed closer together to make them fit on one page.
