The S-type was introduced as an additional model
to the Mk II but with the benefit of the independent rear suspension
from the Mk 10. It retained some of the character of the Mk II and had
ample performance courtesy of the 3.4 or 3.8-litre, six-cylinder XK
engine. The 420 was developed directly from the S-type but resembled the
Mk 10 at the front and rear. The special version of the 4.2-litre engine
gave the model its name. The equivalent Daimler, the Sovereign, bridged
the gap between the 2 1/2-litre saloon and the big Majestic Major. This
is a book of contemporary road tests, specification and technical data,
new model introductions, driver's impressions, long term tests and
buying used guide. Models include: 3.4 and 3.8 S-type, 420, 420
automatic.
