It is indeed Courrier for France.

Yes. The problem is that in France many on the road are imported from neighbourhood countries. But we can assume they are "Courrier" when filmed in France, except if proved otherwise.
Long time ago we decided not to use that local name, but that would not be logical compared to how we list/name other local models.

That's not really a "mass change"

Thank you, I wasn’t aware of that information.

Yeah, but he was there all alone.

However, I made a mistake on the military Nissan model, it’s not "ML-6" but "Patrol ML-6".
And for all Chassis-Code is "260".

No it's not ! The 260 code was applied to the restyled spanish-made Patrols from the late 1980s. But, according to your link (which I posted on this entry two days before you asked... http://www.imcdb.org/vehicle_1304475-Nissan-Patrol-ML-6-160.html ) the ML-6 was introduced in 1988, before that face lift. So code 160 for most of them.

For all these vehicles, the model is "Mustang Boss 302".

For all these vehicles, make is "Grandin" and model is "Dallas".

Should Boss 302 be set as part of the model, or should it stay as complement? snack.com says:

Mach 1 is (mostly) used as part of the name, in IMCDb, but Grandé is always given as complement. Which part is the good one?

It's one of IMCDb's mysteries to me. Trim levels are entered in the extra info field... except when it's a sporty version, then it's written as part of the name.

Because these model usually interest more people, so it makes then easier to find

I've added a comment regarding North American J60 Toyota Land Cruisers on this entry, and their chassis codes.

http://imcdb.org/vehicle.php?id=4472

This means I'll update some of them with the appropriate FJ60 or FJ62 codes. I'm just mentioning this in order to avoid future requests to return them AGAIN to J60.

But we decided long time ago to use only the "generic" J-something code for these...

Which I understand for "classic" Land Cruisers, like the J40 & J70, because they are based on engines and wheelbases, and even I would rather not touch it. But the more recent ones are more structured in that regard.

OK, if there are more easily identifiable we can keep that "generic" rule just for old ones...
But J60 is not much more recent than J70, no?

The pre-facelift Škoda Roomsters have the wrong model year. (Pre-)production started in June 2006 (according to English Wiki) and sales in September 2006. Both dates are in the Škoda model year 2007 since MYs at nearly each VW AG brand starts in May or June. We list them mainly as 2006. BTW all Roomster should get the chassis code 'Typ 5J'.

ok
