Indeed that article seems to announce its arrival
No commercial documents in French, though?

One conflicting example:
https://www.imcdb.org/vehicle_209445-Renault-5-1984.html
Is it an older model? Or a newer one with a modified badge?
Or did both 5 & LeCar coexist?

I'm not sure using "5" as chassis code is good, as a few of them have their real chassis code (R122-something)

Indeed that second image is from a Canadian magazine, but have you searched/found more evidence? Was that change consistent/permanent or did they use both names after that?

Designed by, but not sold by.
Like we have cars designed by other companies than the company directly linked to their make

For all "1979+ Renault 5" for Canada market (Made for CDN).

Model is "LeCar" and chassis-code is "5".
The changeover from 5 to LeCar in Canada was in 1979:

Vehicles for specific markets could be branded "Navistar" and vehicles for the general public could be branded "International".


they still specify: "The International M1224 MaxxPro MRAP (Mine-Resistant Ambush Protected) is an armored fighting vehicle designed by American company Navistar International's subsidiary Navistar Defense".

"Navistar Defense" is the company, not the make. On Wikipedia they still refer these as just Navistar like https://en.wikipedia.org/wiki/Navistar_7000_series
And some still as International: https://en.wikipedia.org/wiki/International_MaxxPro
Maybe some should be changed then, but maybe not all

I just found out that the brand "Navistar" had been created.
https://www.imcdb.org/vehicles_make-Navistar.html

Two of the vehicles referenced are military vehicles that have also been referenced under the make "International".

https://www.imcdb.org/vehicle_1055262-Navistar-MXT-2010.html

Official Make is "Navistar Defense", military branch of Navistar International.
https://www.nddefense.com/
https://en.wikipedia.org/wiki/Navistar_Defense_LLC

So we should rename them under the make "International"?
Or if you want to be correct, rename them under the make "Navistar Defense".
These are the vehicles concerned:

Please Change Vehicle Make For "Asia"
