Theyre driving the car off the lot with a safety defect. And by definition the safety defect presents unreasonable risk of death, crash or injury. Reporter the manager at premiere auto group, he said he discloses recalls too. But then sells the cars. Do you feel like theyre safe with that recall . Theyre not safe. But i mean, its bmw.
