What about the 2010 + the three without year?

Sorry please disregard above, as the trim level changed in 2016, we can't assume that all 2015 are GLS. I'll go through them manually instead.

Add "MkVI" to those without (or remove from those with? As USA & Canada don't use Mk):

fixed Accent & R-Class , 7 pages is too much of a Fiesta for me tonight..

Thanks Baube

For the Ford Focus we used only model years for the North-American models, and mk for the rest of the world. One of the reasons was that the mk2 version was a different car in N-A, but also that indeed N-A does not use much the generation numbers but only model years.

Question for everyone then:
Do we do the same for the Fiesta, as N-A only got the first and sixth?
Or do we label them with mk like the ones of the rest of the world?
(and for any decision, the same should apply to mk1: currently only some have the mk tag)

Not a strong opinion, but would be tidier if N-A Fiestas followed global Mark system even if only 1st and 6th apply there. Stops us getting a cluster of unspecified Fiestas where no year has been entered.

I haven't a definite opinion too because I'm too much accustomed to the Mark system used in Europe, but I understand that using Mks would be maybe weird for American public that only got those two generations. I also see other similar cases, like Focus, Transit/Transit Connect, Saturn Astra etc. doesn't have Mks entered in their American versions.

Well, these have the year, normally

MK shouldn’t be used on NA entries; even some that currently use them Prius and Mitsubishi (i think eclipse).

Most have chassis codes specific to their generation which would separate them without a need for an MK.

For the Prius aren't these often referenced by their generation?
It is not used officially, of course, but by car enthusiasts.

Both Nissan Note and Livina are hatchback

https://www.imcdb.org/search.php?resultsStyle=asList&sortBy=0&make=Nissan&model=- Note
https://www.imcdb.org/search.php?resultsStyle=asList&sortBy=0&make=Nissan&model=- Livina

I think they should be changed the other way...
Wikipedia lists them as mini-MPV:
https://en.wikipedia.org/wiki/Nissan_Note
https://en.wikipedia.org/wiki/Nissan_Livina
The Note is related to the Renault Modus that we listed mostly as MPV:
https://www.imcdb.org/search.php?resultsStyle=asList&sortBy=0&make=renault&model=- modus
(and that Wikipedia also lists as mini-MPV)

Okay, now I think maybe it really looks too large to be a hatchback

Yes, that one is big.
I changed the three to MPV.

Yes, it's a fan thing. I remember a "Mark" was added on Eclipses, Priuses and Supras, because "that's how their fans refer to them". On Eclipses, the "Mk" was quickly changed to "G" (1G, 2G, 3G, 4G) because that's the formulation they used in Eclipse forums. I can't argue with that, but I'm glad it hasn't been expanded to other japanese cars. For some models it would be a minefield.

For the Supra it is widely used

We have 2 Ford Edge with chassis code CD539, 88 with CD539N and 41 with CD53N.
Is there a reason for these three different codes?
