Indeed, for these the "mk" field is not used, as that "Mark" was really part of the name.

Speaking of "Marks," this particular car is a Lincoln Continental Mark IV, but you misidentified it as a "Series IV."

Just thought you'd like to know.

Pour les voitures récentes (années 80 et +) on parle souvent de "phase" pourtant. Pour les plus anciennes, on pourrait mettre "version" ou "série"...

Petite remarque concernant le vocabulaire: ne pourrait-on pas changer le mot "phase", aux connotations un peu trop médiacales à mon goût, par "version" ?

I was discuting about that today with Sixcyl.
The chassis code being between [ ], it is not mixed with the model name, so I guess it is not a problem. For the mk, I do not really know yet how I'll do.
Putting the info on a separate line looks strange, I am not sure it is the best solution
By the way, if somebody has an idea on how we could put these various info on the page in a clean way...
A solution would be a list
Make: ...
Model: ...
Year: ...
etc.
on the left of the picture for example. But it would maybe not look very good

I'll change Opel back to chassis code then.

I think it would be better to put them back there, even if they are somewhat like the Mk:s, especially since we have the earlier P and P2 models that won´t fit in the Mk system.

As for the name order I think it would be better if the Mk field was sorted beneath the make and model field if possible. Maybe even the chassisfield could be sorted there. To keep the official name clean from workshop designations and selfmade numbers.
Like this:
1964 Opel Rekord L
[A]
1968 Mercedes-Benz 200
[W115]
1975 Ford Capri II
Mk2
1975 Volkswagen Golf L
[Typ 17] 1

Some models have the Mk in the name, and in those cases it shold be in the modelfield or extra info, since it´s the official designation.
Like the Triumph 2000 Mk2, but the 2000 Mk1 isn´t badged that way and I think it ws dropped again on the later 2000 TC model. It was still a Mk2 though, of course, even if the label came off.

The european Fords are also problematic since they are produced in both britain and germany. It´s ok for the british cars to have a Mk number, but for other markets it feels more strange since they are rarely (I think) referred to in that way outside the UK. Maybe it´s better to use a simple number like the VW for them?

I thought it was better for Opel since these letters were a little like Mks... (since for Vauxhalls the letters are replaced by Mks).
I can put the letters back to chassis code if it is better.
For the name order, I could make this depend on the make.

Why is the factory given letters of the Opels moved into this field? It´s a kind of chassis code and is better treated like that. There are some generations of Rekord before the A with other codes, for example.

And this field comes between the modelfield and the extra info connected to the modelfield so it splits up the full modelname, like Rekord A L or Kadett A L.

You did not login on the forum I guess (it is separated from the site).

For Cadillac, it seems quite complicated. It is more than just "Mk" followed by a number

About custom cars, for the moment we put the coach builder as extra info, as I said somewhere else this is another problem and we will have to think about it.

Why "anonymous" ? This is "MrCadillac".
