Can't use it if the car isn't registered to you...can't even get hyundai to switch ownership. Guess they are mad they had to replace my entire engine after they failed to inform us about a major safety recall and my engine locked up while going down a highway doing 70. 2 weeks after we got it. Took a month for them to decide if they were going to replace it. Found out they waited for the deadline so we couldn't file a claim for the class action lawsuit we were never told about.
