Can I advertise my canadian car and sell it from Canada?

You should of email and ask owners of this website or read they policy or just try it and see if it takes your zip code and Canada address simple)

Dude Canadians don't have a zip code.The sell my car button doesn't exist on the car.cargurus.com site

Yes, You just need to lay out the money to purchase a car dealership, put your car in inventory, and then advertise your inventory with CarGurus

Canuks cannot sell their cars on CG's.
