Give me a list of all North American car company's?

Well it seems as if the USA doesn't have much "Car" company's. For instance, these are all of the North American car companies I can name right on the spot, Chevrolet, Dodge, Ford, GM, Mercury, Saturn, Buick.

But on another page, I feel as though Europe has more car company's than North America. Prove me wrong. :^)
BTW, for what it's worth i was born and raised in North America.

Chrysler, Chalmers, Chalmers-Detroit, DeSoto, Eagle, Fargo, Jeep, Imperial, Plymouth, Ram, Valiant, Ford, Continental, Lincoln, Mercury, Edsel, GM, Buick, Marquette, Cadillac, La Salle, Chevrolet, Geo, GMC, Hummer, Oakland, Pontiac, Olds Mobile, Saturn, American Motors, Avanti, De Lorean, Detroit Electric, Falcon, Fisker, Henessey, Polaris, Shelby, SSC, Tesla,

There are probably 1000 more, don't think Europe has more car companies, many car companies exist but are rare and have probably failed. Europe is the same way, only a few survive.

Well I consider that America only has 3 companies
GM, Chrysler, and ford
Because every car "company" from north America
Is owned and manufactured by these big 3
