Yes sounds good to me.

I checked previously and dsl updated the few classic ones without code, but there are still some Moke without code, I forgot about these.
Anyway with both solutions those without chassis codes will cause issue.
I can do the uppercase only for the R/F/U codes, but then all the newer ones without code should get one (one by default if the picture does not allow to chose precisely which one they are).

Oh yes I forgot about the latest U ones. There should be some classic Minis listed without the chassis code though so it might be better not to put the uppercase to all of them.

I forgot that, I'll try to do that in the next days.
There is also U, and all those without code. So the other way seems easier: uppercase when chassis is not starting by AD.

@Antp: I think we can put MINI in capital for all the chassis codes starting with R (R50, R52, etc...) and F (F55, F56 etc...) to make things quicker.

It is fine These fields are there if we want to add info when it is available, but it can also be quite empty if we don't have more.
Also, most of the existing 6000+ makes still don't have anything, since they were created automatically.
For recent makes it is easier to have info and logo of course.
Like here I've put the full company name, website link, and (one of the reason of this) a link to a related make: https://www.imcdb.org/vehicles_make-Suzhou-Eagle.html
When there is a Wikipedia page, I also sometimes included the first sentence of the page as description. Like here, where there is also the link to the other make sharing the name: https://www.imcdb.org/vehicles_make-Triumph.html

Update: have filled in some basic info on Serra, and after mike962 found a leaflet on Transcraft. Still only bare bones stuff, but not sure what else there is.

Another new make here - claimed to be Transcraft and I believe them. But can't find any info to fill any boxes.

I've just added a new make - Serra - for this thing. Can't find a wiki page to fill in the box, or a logo or model list, so could only enter that it's Spanish. Result the make page is a bit bare on detail. However there is info out there - eg here or here.

So questions: have I done it right?? is there info from my 2 links you want to add to the make info??

You can create a new make either from the home page or from the "all makes" page: there is a "add make" link above the list of makes.
Some day later I'll maybe add such possibility directly in the "edit vehicle" page, but as there aren't so often new makes it was less urgent.
