How do I get rid of a car on my property?

I hope someone here can help me or point me in the right direction with this one.

I have a car that I need to find someway to get rid of that is being stored in my garage. I let a "friend" store it in my garage nearly 8 years ago when he had to move out of state. The deal was he would get settled in at his new location and retrieve the car from me then. For a few years I kept getting excuses whenever I asked when he was coming back for the car. As time went by he slowly stopped answering any messages from me. I haven't talked to him or gotten a reply from him in over a year, and his mentions of dealing with the car stopped probably two years ago.

It's in a my residential garage. The plates are expired, I can't find a key for it (if that would do any good since it hasn't been started since it was brought in), and the guy never gave me a title to it when he dropped it off.

Is there a way for me to have it declared abandoned or something along those lines? All I want is to find a way to get rid of it, preferrable at little or no cost to me.
