Completely unrelated, but I see on https://es.wikipedia.org/wiki/IKA-Renault_Torino that the name changed from IKA to IKA-Renault in 1970 (that seems to be correct on the site for those with a year) but then to just Renault in 1975, though that we list as Renault only the 1979+ models.
Maybe something to change for the 1975-1978 models?

Also those without year are currently split between IKA and IKA-Renault, without clear logic Maybe we should put the yearless models as just IKA by default.
