I wrote an article on the subject. I'd love to discuss the facts.

They tried to make the 1969 Mark III more exclusive so they furthered the 1958 lore and didn't put the word Lincoln anywhere on he car, but the title. All but a few aberrations are titled as Lincolns. They didn't lie this time, they just chose their words more carefully.
When I got the aqua Mark III slicktop people started sending me literature. My friend, Al Gorosh, gave me a Mark III brochure that was unusual. It contains actual photos, not printed pages. It is clearly marked CONFIDENTIAL in gold lettering. I believe this is an introductory piece given to Ford executives, members of the BOD and dealers. None of the cars pictured have headrests required early in 1969. Often called the "1968 1/2", but even that's not true as every Mark III serial number starts with a 9 for 1969. There isn't a single title, parts book or service manual that uses "1968 1/2". It just denotes a running change to accommodate mandatory safety changes.

Here's the first page of the brochure. How can anyone dispute this?

The rest of the brochure.



Note that the colors are not all that they offered. It shows the vinyl top as optional.


Marti Reports are generated off of access to Ford's data base. They clearly shows the car as a Lincoln Continental Mark III.
Why do people persist in claiming that the '58, '69 and subsequent Marks are somehow not a Lincoln when they were built on the same assembly line as the Thunderbird and other Lincolns, put together by the same workers, picking many parts from the same bins. You would have to believe that somehow the Continental Division lived on, but there is zero proof of this. I would believe it if 3 items were cleared up. Where did they move after Edsel occupied Continental's offices in November of 1956? Who led the Division? We know where William Clay Ford went, so, who headed the Mark projects?
It's very nice to think your special car is somehow not a Lincoln, but facts matter.
