Cars: What should I do?

My boyfriend is a mechanic and also buys and flips cars. A week ago, I bought a car that he thought would be better for me than my Honda. So, I bought it but I haven't received the title. We went to the auction and got it. He told me it will cost $100 for the title. No problem but he keeps saying that he will give me the paperwork to register the car. But recently, he involuntarily thought it was okay to take us and his friends on a road trip in my car without telling me. He uses my car daily while he has multiple cars of his own.

Also, he keeps pushing me to sell my old car and to give him my title. I want to keep it and he knows it. I don't know what's going on with him. It's not like he lets my car sit at my place or even his place, but he drives it daily despite the fact that my old car is unreliable

You maybe breaking the law by allowing him to drive it without insurance.

Sounds to me like he's using you. And it may be for something illegal. Do some serious checking on this dude.

The car isn't registered and it probably isn't insured either, both of which are highly illegal. If he gets stopped by the police or gets into an accident YOU will be liable for the fines and damages. Stop being a pushover and do not let him get away with this. Also, when you do get the car registered and titled in your name, dump that creep. You're associating with the wrong sort and you;ll just be skipping from crisis to crisis with him until you do. At least keep your knees together until he straightens up

EPIC FAIL.
