Abandoned vehilce solution?

[Richard Arden]

I share a duplex with my only tenant. He has an old navigator thats broken and unregistered. No effort has been put into repair or selling. I have in the lease that no abandoned or unregistered vehicles should be stored at the property. I have brought up a few times in conversation that he needs to get rid of the thing but nothing formal or official. I was going to send a 30 day notice for removal. But what actions can I legally take if he fails to comply? A fine, tow at owners expense? I dont want to evict for terms on something like this.
