Hi
The Hallmark has slightly more sytlings.
It had Bilston Suspension, Alpine Wheels, Alpine Front Spoiler, Hand
painted coach line down the side with an "H" at the rear, a line
under the 633csi badge on the boot, a line around the front spoiler
with an "H" on each side, The steering wheel was a motorsport version
with a sterling siver badge in the centre (as per the seat head
rests) the ashtray had a sterling silver hallmarked cover with a "H".
All of the 26 cars produced had automatic gearboxs with the exception
of two.
One of these was owned by Derek Bell and features in an article in
Brookland Books - BMW 6 Series - Gold Portfolio 1976 - 1989.
The Total BMW feature was in January 2001. The car featured is the
one located in Scotland, I beleive.
A specific BMW brouchure was produced for the Hallmark which does
turn up on ebay rarely but expect to pay £30 +.
It is hard to put a price on these cars as there seems to be so few
around.
A car is only worth as much you are prepared to pay at the end of the
day.
Oh, by the way I have owned the other Manual since 1980.
Happy Motoring
