Thanks everyone. I guess it may just be a marketing issue, which
differs from country to country. The badge on the back just says "XJ
Executive" (no reference to the no. of cylinders) and that is repeated
on the registration papers.

But there is no doubt that there is an in-line six under the hood!
Anyway here they offered the six in 3.2, 4.0, and supercharged 4.0
form.

The XJ6 3.2 and 4 litre 6 cylinder cars were discontinued in October
1997.  The production of the first XJ8 3.2 and 4 V8 commenced in late
October 1997.  In Australia the cars come with a Jaguar plate at the
front near the radiator top which is a JAguar plate giving chassis and
engine and trim codes.  The car also comes with a build date plaque
and compliance plaque affixed to the floor pan under the battery
compartment cover in the boot (Trunk).

The build date plaque is a requirement of the Australian compliance
authorities and tells us the monthand day the car rolled off the line
as well as which ADR and international design rules the vehicle
complies with.  Thus I have a car which is a 3.2 XJ6 Sport built in
August 1996, complianced in Australia in December 1996 and sold to its
fisrt owner on 21 June 1997.

All countries are different but in all cases the 6 Cyl XJ ceased in
production in early October 1997.
