Answer

this the best solution to solve it

def _get_cars_domain(self):
    print (self.company_id.car_ids)
    return [('id', 'in', self.env.user.company_id.car_ids.ids)]

car = fields.Many2one(comodel_name="cars", store=True, string="Car", ondelete='restrict', required=False,domain=_get_cars_domain)
